Counting parts by hand is inefficient, inaccurate and impractical. Whereas it may be suitable to count ten pieces into a package, it becomes cumbersome and unwieldy to count twenty five, fifty or one hundred pieces by hand. It becomes downright impossible to accurately count one thousand pieces or even more by hand. Parts counting scales are an ideal tool to use for counting parts that are identical in weight. Items such as bolts, screws, nuts, rivets, washers and other fasteners would fit this criteria. Similarly, electrical contacts, connectors, resistors, diodes, and integrated circuits would also be suitable. The scale operator places a small sample of parts on the digital scale platform, and through the keyboard, enters the number of parts in the sample. The industrial scale then calculates the weight of a single part. At this point, as parts are added [+]

Counting parts by weight is an efficient means of determining inventory levels. Any item that is consistent in weight may be counted by a parts counting scale. These items can include standard industrial hardware, such as fasteners, washers and clips. Electronic devices are another perfect item to count by weight. A good parts counting scale must have two primary features. It must have enough capacity to accept the full containers of parts. And it must be sensitive enough to accurately determine the weight of just a few sample parts. These two characteristics are often mutually exclusive. As a rule, the higher the capacity of the scale, the lower the sensitivity. The accuracy of the weight of the sample parts is the largest factor in determining the accuracy of the parts counting results. As [+]
