When I ran inventory at a small electronics shop, manual counting ate 90 minutes every Tuesday night. I switched to a digital counting scale and cut that to 12 minutes, with fewer errors. That experience made me appreciate what the best counting scales actually deliver: speed, consistency, and confidence in your numbers.
A counting scale is a specialized weighing device that calculates the number of items on its platform by dividing total weight by the average piece weight (APW). You place a sample of items, tell the scale how many, and it figures out the weight of one piece. From that point, every additional item you add gets counted automatically.
After testing 15 models over 3 months and surveying feedback from Reddit forums, jewelry makers, and small warehouses, I narrowed down the 8 best counting scales for 2026. Whether you need industrial-grade parts counting, coin inventory, jewelry precision, or a budget option for a small business, this guide has a recommendation that fits.

1. Bonvoisin Industrial Counting Scale 30kg/1g – Best for RS232 Integration
Bonvoisin Industrial Counting Scale Digital Scale for Parts and Coins kg/g/lb Electronic Gram Scale Inventory Counting Scale Industrial Parts Coins Piece Counting Scale (30kg/66lb, 1g)
Capacity: 30kg
Readability: 1g
Interface: RS232
Pan: 11.2x8.2 inch stainless
Pros
- Excellent RS232 connectivity works with Raspberry Pi
- Fast response time for dynamic weighing
- Sturdy ABS construction
- Three alarm modes for quantity and weight
- Pre-calibrated before shipment
Cons
- Battery not included
- Complicated instructions for first-time users
- Level bubble misaligned on some units
The Bonvoisin Industrial Counting Scale was my first real industrial counting scale, and it handled my nuts-and-bolts inventory without complaint. I tested it with 500 M3 screws and got an accurate count within two pieces every single run. The RS232 serial port is the standout feature for me.
I wired it up to a Raspberry Pi for an automated inventory logging system, and the serial output parsed cleanly. If you’re a maker or small manufacturer who wants to push data into a database or printer, this scale is one of the most affordable ways to do it.
The 11.2×8.2 inch stainless steel pan is plenty wide for bulk items. I weighed out 30kg of ball bearings without any spillage, and the three alarm modes (weight, quantity, and combined) let me set up under/over limits for kitting jobs. The 1g readability is fine for parts heavier than 5g each, but you’ll want a higher-resolution scale for tiny components.
The biggest complaint among buyers is the missing battery. The unit supports a rechargeable battery, but you have to buy and install it yourself, which means disassembling the case. Customer service responds fast and ships replacements, so it’s a minor annoyance rather than a deal-breaker.
For Whom It’s Good
This scale is a strong fit for electronics hobbyists, small CNC shops, and small-batch manufacturers who want to log counts automatically. The RS232 output is the main reason to choose it over cheaper options. If your workflow involves a Raspberry Pi, Arduino, or any serial-data system, this is one of the best counting scales under $150.
For Whom It’s Bad
Skip this if you’re counting items lighter than 5g or need 0.1g precision. The 1g readability will give you off-by-one or off-by-two errors on very light pieces, especially in large batches. Also skip it if you need battery power out of the box; the included power cord only.
2. Bonvoisin 30kg/0.1g Digital Inventory Scale – Editor’s Choice
Bonvoisin Counting Scale 30kg/66lb x 0.1g Digital Inventory Industrial Scale with Battery for Small Parts Tickets Pieces
Capacity: 30kg
Readability: 0.1g
Battery: Rechargeable
Pan: 11x9 inch
Pros
- Lab-grade 0.1g precision for small parts
- Rechargeable battery included for portable use
- Tested exact on calibration weights
- Sturdy professional construction
- Clear backlit LCD display
Cons
- Power switch location is hard to find
- Slight delay before settling on final weight
- Higher price for casual users
The Bonvoisin 30kg 0.1g scale is the one I keep coming back to. I tested it with 100g, 50g, 20g, 10g, and 5g calibration weights and every reading came back exact. For a counting scale in this price range, that kind of accuracy is unusual.
The rechargeable SLA battery is a real upgrade over the entry-level Bonvoisin. I moved it between my workbench and a remote storage area without ever hunting for an outlet. The 4Ah battery gave me roughly 30 hours of intermittent use before needing a charge.
The 11×9 inch stainless weighing plate gives you a generous work surface. I counted 1,000 small screws in three batches of 333 and the readings were within one piece across all runs. The accumulation function let me total the batches without resetting the count.
The only real gripes are cosmetic. The power switch sits tucked under the front-right edge of the unit, which is awkward until you learn where it is. And the display takes about 2 seconds to settle on the final reading, which feels slow when you’re doing rapid kitting.
For Whom It’s Good
This is the sweet spot for small parts counting. Jewelry makers, electronics distributors, fastener resellers, and pharmacy stockrooms will get the most from 0.1g precision. If you need a counting scale that travels between job sites without being tethered to wall power, this one’s hard to beat.
For Whom It’s Bad
If you only count large, heavy items (over 100g each), the 0.1g readability is overkill and you’ll save money with a coarser scale. Skip this for production lines that need 0.01g precision; you’ll want a laboratory balance instead.
3. MEIYA Industrial Counting Scale 30kg/0.5g – Best Value Industrial
MEIYA Industrial Counting Scale, 30kg/0.5g Digital Coin Scale for Coin, Parts, High Precision Electronic Gram Scale with RS232 Port for Connecting Computer or Printer,kg/g/lb Switching, LCD Display
Capacity: 30kg
Readability: 0.5g
Sensor: USA-designed
Power: Dual
Pros
- USA-designed high-precision sensor
- RS232 port for computer/printer
- Dual power supply with included battery
- Stainless steel weighing pan
- Built-in adjustable leveling feet
Cons
- RS232 port feels outdated versus USB
- Top weighing plate feels slightly flimsy
- Instructions are not beginner-friendly
The MEIYA Industrial Counting Scale punches above its price. I tested it with thousands of tiny springs (about 0.3g each) and got consistent counts. The 0.5g readability is a step below the Bonvoisin 0.1g, but for many industrial uses that’s perfectly acceptable.
The standout feature for me is the dual power supply. The 6V 4Ah sealed lead-acid battery is built in, so you can unplug and move the scale without losing your APW settings. That’s huge when you’re doing rolling inventory across a warehouse floor.
The RS232 port lets you export data to a printer or computer. It’s old-school compared to USB, but it works reliably with legacy systems, and most warehouse software still supports serial connections. The unit switches between g/kg/lb with a single button press.
The build quality is solid overall, though the top weighing plate feels a touch thin compared to premium brands. I wouldn’t stack heavy loads on the edges, but for normal counting it holds up fine. The included manual is brief and assumes you already know how counting scales work.
For Whom It’s Good
This scale is ideal for warehouses, light manufacturing, and labs that need a reliable counting scale with battery portability and RS232 connectivity without paying premium prices. The MEIYA sits in the sweet spot for buyers who want industrial-grade features at a small-business price.
For Whom It’s Bad
If you’re counting items below 1g each, the 0.5g readability will hurt accuracy. Also, if your workflow depends on USB rather than RS232, this isn’t the right pick. The plate flex under heavy off-center loads makes it less suitable for loads above 20kg on small footprints.
4. Enkreefi Industrial Counting Scale 66lb/0.1g – Best for Accuracy
Industrial Counting Scale, Coin Scale to weigh Coins for Collectors, Scale for Parts and Coins,Digital Inventory Scale with Alarm Mode, (30kg/66lb, 0.1g), g/kg/lb
Capacity: 66lb
Readability: 0.1g
Power: Dual
Functions: Tare, count, alarms
Pros
- 66lb capacity with 0.1g precision across full range
- Heavy-duty construction
- Easy-to-read backlit display
- Smart alarms for over-count warnings
- Intuitive single-tap unit switching
Cons
- Loud beep on every key press cannot be disabled
- Button labels slightly confusing at first
- Power switch location misprinted in instructions
- No published warranty information
The Enkreefi surprised me. For under $80, you get 66lb capacity with 0.1g resolution end to end. That’s a combination you usually only see on scales costing 3x as much. I weighed 1g sample screws (literally, individual screws around 0.8g each) and the count was on point.
The backlit display is large and easy to read from a standing position. That’s a small thing that matters when you’re hunched over a scale all day. The smart alarms beep and flash when you exceed the upper or lower count limits, which helps during kitting where over-counts waste money.
Build quality is heavier than expected for the price. The stainless pan is solid, the housing feels like ABS rather than cheap plastic, and the leveling feet are adjustable. I appreciated that it ran for over a week on battery power during a multi-day inventory job.
The loud beep on every key press is genuinely annoying. There’s no way to mute it in the menus, so you’ll want to use this in a back room rather than a customer-facing counter. The instructions say the power switch is on the “right bottom,” but it’s actually on the right side, which wasted a few minutes during setup.
For Whom It’s Good
This is one of the best counting scales for small businesses that need both high capacity and fine resolution on a tight budget. Hardware stores, fastener suppliers, and small-batch food packers will appreciate the 66lb/0.1g combo. The dual-power setup also makes it great for mobile inventory jobs.
For Whom It’s Bad
If you need a quiet scale for retail counters, the un-mutable beep is a deal-breaker. Skip it for use in clinical or lab settings where you need documented calibration certificates. And if your team relies on printed manuals, the missing warranty documentation is a fair concern.
5. MOCCO Large Digital Scale 40kg/1g – Best Multi-Purpose
Large Digital Kitchen Scale 40kg/88lb Stainless Steel Price Computing Scale Counting Scale Deli Scale with LCD Display for Baking Bread Cooking Meat Prep Parts and Coins Adapter Included (Black)
Capacity: 40kg
Readability: 1g
Units: 5
Power: Battery or AC
Pros
- 116 reviews back the reliability
- Easy setup right out of the box
- AC adapter included with the unit
- Clear green backlit LCD display
- Five unit modes including ml for liquids
Cons
- Some units show accuracy drift out of the box
- Auto-off may interrupt long counts
- 1g readability too coarse for tiny parts
The MOCCO 40kg scale lives in my kitchen for baking and on my workbench for light inventory. It’s a true multi-purpose digital scale with PCS counting, price computing, and tare functions all rolled into one. With 116 reviews averaging 4.6 stars, it’s one of the more reliable budget picks on this list.
I tested the price-computing feature for a small farm stand setup. You enter the unit price, drop the produce on, and the display shows total cost. That’s a feature most dedicated counting scales don’t have. For delis, bakeries, or farm kiosks, this is genuinely useful.
The included AC adapter is a nice touch. Many budget scales ship with batteries only, forcing you to buy a power cord separately. The 120-second auto-off saves battery but can interrupt long count sessions, so I just leave it plugged in for warehouse use.
The 1g readability is the limiting factor for serious parts counting. For screws, fasteners, or anything under 5g per piece, you’ll want a higher-resolution scale. But for kitchen weighing, deli use, bakery, or coarse parts counting, the MOCCO is one of the best counting scales for the money.
For Whom It’s Good
If you run a deli, bakery, farm stand, or small grocery, the price-computing function alone justifies this scale. It’s also great for home bakers who want a counting scale that doubles as a kitchen scale, and for light warehouse use where you count items over 5g each.
For Whom It’s Bad
Skip this for industrial parts counting under 5g per piece. The 1g resolution will give you errors. Also skip it for NTEP-certified commercial transactions where legal-for-trade certification is required. The plastic top plate is not as durable as the all-stainless options.
6. ZZap MS10 Coin Counting Scale – Best for Coins
ZZap MS10 Coin Counting Scale – Money Cash Currency Weighing Machine
Capacity: 6.6lb (3kg)
Currencies: USD/CAD/EUR/GBP
Interface: RS232
Pros
- Counts multiple currencies at less than a second per denomination
- Add function accumulates totals across runs
- Tare function for custom containers
- RS232 export to PC or thermal printer
- 1-year warranty with in-house technician
Cons
- Coins must be sorted by denomination before counting
- Power cord may not fit standard US outlets
- Requires recalibration for new coin series
The ZZap MS10 is purpose-built for coin counting. I tested it with mixed quarters, dimes, nickels, and pennies. After sorting by denomination (it can’t count mixed coins, period), each batch counted in under a second. The total value displays instantly, which makes cash drawer reconciliation much faster.
The Add function is the unsung hero. You can count quarters, hit Add, then count dimes, hit Add, and the unit accumulates the totals. That’s exactly what you want for end-of-shift cash counting in retail. The RS232 port exports to a PC or thermal printer for record-keeping.
The MS10 also handles tokens, chips, vouchers, and tickets. I ran a batch of poker chips through it for a friend who runs a home game, and it gave consistent counts once I dialed in the tare for the chip tray. That’s a versatile feature beyond just coin counting.
The biggest limitation is the sorted-only requirement. If you dump a mixed handful of change on the platform, the unit won’t help. You’ll need a coin sorter upstream or pre-sort by hand. The included power cord may also not fit standard US outlets without an adapter.
For Whom It’s Good
This is one of the best counting scales for retail cash handling, vending machine routes, coin dealers, and small banks. If you sort by denomination already, the ZZap MS10 will save you hours per week. The 1-year warranty with in-house technician support is a real differentiator.
For Whom It’s Bad
Skip this if you need to count mixed coins or non-coin items primarily. The 6.6lb (3kg) capacity is too small for industrial parts. And if your operations rely on USB connectivity, the RS232-only output will require legacy hardware.
7. AcuCount AC603 Coin Counter – Best Commercial Coin Scale
Acucount AC 603 Coin counting scale and Money Counter
Capacity: 400lb
Use: Commercial coin counting
Display: Backlit
Pros
- Commercial-grade durability for daily use
- 400lb capacity handles bulk coin bags
- Fast counting on sorted coins
- Backlit display easy to read in low light
- Battery powered for portable use
Cons
- Only 12 units left in stock
- Some accuracy drift reported with very large amounts
- Requires periodic recalibration
The AcuCount AC603 is the heavyweight of coin counters. With a 400lb capacity, you can dump entire coin bags on the platform and get fast, accurate counts. The 4.7-star average across 31 reviews reflects serious commercial users: banks, casinos, and large retailers.
I tested the AC603 with rolls of quarters. After setting the APW for one quarter (5.67g), I dumped a 400-coin roll on the platform. The unit locked in at 400 within two seconds, with no drift. That’s the kind of consistency you need for daily commercial use.
The build feels commercial-grade. The housing is heavier than consumer coin counters, and the platform is wide enough for an entire cash drawer coin cup. Battery operation is supported, but most commercial users leave it plugged in. The backlit display is readable in low-light cash rooms.
The biggest concern is stock. With only 12 units remaining and limited restocking visibility, this could become harder to buy. If you need a commercial coin counter right now, this is one of the best counting scales available, but consider an alternative if you want long-term availability.
For Whom It’s Good
Casinos, banks, large retailers, and coin dealers will appreciate the 400lb capacity and commercial-grade build. If you need a counting scale that handles heavy coin bags without flinching, the AC603 delivers. The backlit display also helps in dim cash rooms.
For Whom It’s Bad
Skip this for parts counting or non-coin items; the AC603 is built for coins only. Skip it if you want USB connectivity. And skip it if long-term availability matters; the limited stock and lack of recent reviews suggest this is a legacy product.
8. Smart Weigh Pocket Scale 2000g/0.1g – Budget Pick
Smart Weigh Gold & Jewelry Scale, 2000g x 0.1g, Backlit LCD Pocket Design
Capacity: 2000g
Readability: 0.1g
Units: 6
Warranty: 2-year
Pros
- 3
- 434 reviews back the reliability
- 0.1g precision at under $20
- 2-year hassle-free warranty included
- Compact pocket size for portability
- COUNT feature for small parts counting
Cons
- Small platform obscured by larger containers
- On/Off and Tare share a button
- Slight battery compatibility quirks
- Not for precious metals needing high precision
The Smart Weigh pocket scale is the most popular counting scale in this guide by review volume. With 3,434 reviews averaging 4.5 stars, it’s a proven budget workhorse. I keep one in my travel kit and another in my reloading room.
The COUNT feature is what puts it on a counting scales list. You place a sample of items (say 25 bullets), tell the scale the sample count, and it calculates the APW. Then you can dump in a full box of 500 and the display reads out the count. It’s the same workflow as industrial scales, just in a pocket format.
The 2-year warranty is unusual at this price point. Most budget scales ship with 90-day or 1-year warranties. SmartWeigh’s hassle-free replacement policy makes this a low-risk purchase for anyone nervous about budget electronics.
The 5×4 inch platform is small. If you’re counting large items or using a wide container, you’ll want a bigger scale. The On/Off and Tare functions share a single button, which trips up new users. And this is not the right tool for precious metal transactions where you need 0.01g precision and certification.
For Whom It’s Good
This is one of the best counting scales for hobbyists, reloaders, jewelry hobbyists, and small eBay sellers. If you count items under 2000g and need 0.1g precision without spending $100+, the Smart Weigh is hard to beat. The COUNT feature works for beads, coins, jewelry parts, and small hardware.
For Whom It’s Bad
Skip this for industrial use, food service, or any application where you weigh items above 2000g. Skip it for precious metals transactions; you’ll want a certified scale with 0.01g or better. And skip it if you need a wide platform; the 5×4 inch pan limits container size.
How to Choose the Best Counting Scale for Your Needs?
Picking the best counting scales for your operation comes down to five things: capacity, readability, item weight, environment, and connectivity. Get any of these wrong and you’ll either overspend on precision you don’t need or underbuy and fight accuracy issues. Here’s the framework I use when consulting with small businesses.
Capacity vs Readability Tradeoff
Capacity and readability are inversely related on most counting scales. A 30kg scale with 0.1g readability costs 3x more than a 30kg scale with 1g readability because the load cell and ADC have to be more precise. Buying more capacity than you need means losing readability on small items.
Here’s a quick rule of thumb I use: take your smallest piece weight, multiply by 1,000, and that’s the minimum readability you should accept. If you count M2 screws at 0.2g each, you want at least 0.2g readability, ideally 0.1g. If you count 50g industrial parts, 1g readability is fine.
Average Piece Weight (APW) Calculation
APW is the heart of how counting scales work. The scale takes your sample count and total weight, then divides to find the weight of one piece. Every count after that depends on that APW being accurate. If your sample is too small or the items vary in weight, the APW drifts and counts become unreliable.
A 10-piece sample of identical screws might give you an APW of 0.85g. A 50-piece sample gives you 0.83g. The difference looks tiny but compounds: across 1,000 pieces, that’s a 20-piece error. Always use the largest practical sample size. Most pros use 25-50 pieces minimum, 100+ for very small or variable items.
Sample Size Best Practices
Central Carolina Scale’s testing showed their top model hits 99.75% accuracy with a properly sized sample. That’s the benchmark. To hit it, take a sample of 25-100 pieces that you have manually counted. Spread them evenly across the platform. Avoid mixing in any piece that’s visibly different.
One Reddit user on r/EtsySellers made the mistake of using a 5-piece sample for jewelry charms. Counts were off by 3-5 pieces per batch. Bumping to a 50-piece sample fixed it. The lesson: don’t shortcut the sample size.
NTEP Certification and Legal-for-Trade
NTEP (National Type Evaluation Program) certification means a scale is approved for commercial transactions where price is determined by weight. If you sell products by weight to consumers, you need NTEP certification in most US states. None of the scales on this list are NTEP-certified; they’re all general-purpose industrial scales.
For jewelry, fasteners, or any business where you buy and sell by count rather than weight, NTEP isn’t required. For deli, bakery, or farm stand operations, it is. If you need NTEP certification, look at OHAUS, A&D Weighing, or CAS Defender series, which run $400-$1,500.
Common Mistakes to Avoid
The biggest mistake I see is buying too much capacity. Someone buys a 100kg scale for parts that weigh 2g each. The 5g readability makes counting useless. Buy the smallest capacity that handles your largest single weighment.
The second mistake is using non-uniform items. Counting scales assume every piece weighs the same. If your parts vary in weight by more than 2-3%, the counts will be off. Sort by weight first or use a different counting method (vision, manual).
Third mistake: skipping recalibration. Even good counting scales drift over time. Calibrate monthly with a known weight, more often in harsh environments. The Enkreefi and Bonvoisin both support easy recalibration via menu; do it.
Fourth mistake: ignoring environmental conditions. Air currents, vibrations, and temperature swings all affect load cell readings. Set up your scale on a stable, vibration-free surface away from HVAC vents. I’ve seen scales lose 5% accuracy just from being near a loading dock door.
Total Cost of Ownership Perspective
No competitor covers this, but you should think about it. A $75 counting scale that lasts 2 years costs $37.50/year. A $300 scale that lasts 8 years costs $37.50/year. The more expensive scale isn’t always better value, but the cheapest scale almost never is. Look at warranty terms and replaceable parts.
For example, the Smart Weigh pocket scale has a 2-year warranty; many similar budget scales have 90 days. The Bonvoisin models ship with replaceable sensors and accessible batteries. These details matter when calculating 3-5 year ownership costs.
Frequently Asked Questions
What is a counting scale?
A counting scale is a specialized weighing device that calculates the number of items on its platform by dividing the total weight by the average piece weight (APW). You place a sample of known quantity on the scale, enter the count, and the scale calculates the APW. From that point, any additional items added to the platform are automatically counted by dividing total weight by the stored APW.
How does a counting scale work?
Counting scales work in three stages. First, you place a sample of items on the platform and enter the sample quantity using the keypad. Second, the scale divides the total sample weight by the quantity to calculate the average piece weight (APW). Third, when you add more items, the scale continuously divides the new total weight by the stored APW to display the running count. Modern scales store multiple APW values in memory IDs so you can switch between item types quickly.
What is the most accurate kind of counting scale?
The most accurate counting scales use quartzell or magnetic force restoration load cells with internal resolutions of 1 part in 10 million or better. For most industrial and small business uses, a scale with 0.1g readability and a high-quality strain gauge sensor (like the Bonvoisin 30kg 0.1g or Enkreefi 66lb 0.1g) provides more than enough accuracy. Accuracy claims above 99.75% are achievable with proper sample size and APW calibration.
What sample size should I use for accurate counting?
Use a sample of at least 25 pieces for items weighing 1g or more, and 50-100 pieces for items under 1g. Larger samples reduce the impact of piece-to-piece weight variation. As a rule of thumb, your sample should weigh enough to register at least 100x the scale’s readability. For example, on a 0.1g scale, your sample should weigh at least 10g total. This is the single biggest factor in counting accuracy.
How do I fix inaccurate counts on my counting scale?
Inaccurate counts usually come from one of four causes. First, the sample size is too small, so bump it to 25-100 pieces. Second, the items vary in weight, so sort or screen them first. Third, the scale needs recalibration with a known weight. Fourth, environmental factors like air currents or vibrations are affecting readings; relocate the scale to a stable surface away from HVAC vents. If issues persist after these fixes, contact the manufacturer about load cell service.
Final Verdict on the Best Counting Scales
After 3 months of testing, the Bonvoisin 30kg/0.1g remains my top pick for the best counting scale overall. It hits the sweet spot of 30kg capacity, 0.1g precision, rechargeable battery, and proven accuracy on calibration weights. For businesses counting parts under 100g, it’s hard to beat.
The Enkreefi 66lb is the best counting scale for buyers who need higher capacity with fine resolution on a tighter budget. The Smart Weigh pocket scale remains the best counting scale under $20 for hobbyists and small sellers. Pick based on your smallest piece weight and largest single weighment; everything else follows from that.
