For help choosing a counting scale for your parts, call MNM Scales at (832) 290-3120 or email mnmscales@yahoo.com.
The MNM IDS-812 counting scale can be useful for hardware, fasteners, electronic components, packaged fittings and stockroom parts because it combines piece-counting software with a large 12 x 9 inch pan and 15 kg / 33 lb capacity. Instead of counting hundreds of similar items by hand, the operator establishes an average piece weight from a sample and the scale estimates quantity from total net weight.
How Piece Counting Works
A counting scale divides the measured net weight by an average piece weight. That makes sample quality critical. If ten screws vary noticeably in weight, a ten-piece sample can produce more count error than a larger representative sample. Whenever possible, use a larger sample drawn from the same production lot and verify the result by manually counting a second batch.
Best Parts for Weight-Based Counting
Good candidates include machined fasteners, washers, clips, connectors, fittings and other items whose individual weights are reasonably consistent. Poor candidates include parts with large manufacturing variation, mixed models, items carrying oil or debris, and pieces so light that one item produces almost no detectable weight change at the scale's actual configured resolution.
Use Tare for Bins and Containers
Place the empty bin or tote on the pan and tare it before adding parts so the displayed count is based on net contents. The IDS-812's wide platform helps support practical stockroom containers, but the bin must remain stable and should not touch a shelf, wall or other object that bypasses force around the scale.
How to Improve Counting Accuracy
Verify zero before sampling. Use a larger sample size. Keep sample and counted stock from the same lot when piece weights can vary. Avoid vibration. Relearn average piece weight when the part changes. Periodically compare the indicated count against a manually counted batch. If small quantities are critical, remember that counting error can be dominated by piece-weight variation even when the scale itself is functioning correctly.
Why Capacity Matters
The 33 lb / 15 kg range allows the same bench to handle both a representative sample and larger bulk quantities. For very tiny pieces, however, a lower-capacity balance with finer verified readability may count more reliably. Choose the scale around both the maximum batch weight and the minimum individual part weight, not capacity alone.
