For fast and accurate counting, users simply place a known quantity of what they wish to count on the scale and press the dedicated Sampling Key or, for components where unit weight is known, simply input the value on the dedicated APW key. The scale will automatically display the total count of all parts on the pan as well as calculate and display the unit weight of the part. Users can start with a small sample size of 10, and then add random lots of pieces (below original sampling size) to increase their APW accuracy. The software in the machine automatically updates and enhances its average piece weight data as components are loaded onto the pan during counting. If the total weight or APW is too low, the EC Counting Scale will warn the user with a warning on the LCD panel.
The Ohaus EC Series is the most affordable line of parts counting scales they have to offer. Designed with portability in mind, the EC3 features a built-in handle so you can carry the parts counter to different locations throughout your facility quite easily. 3 separate LCD displays indicate weight, average piece weight and total counts. Select from 4 different models with varying capacities and readabilities.
Ohaus EC Series Counting Scales are economical and designed for fast, accurate operation. Ideally
suited for annual inventories, parts rooms, rentals and other counting applications, with an internal
counting resolution of 1:600,000, OHAUS EC Counting Scales offer accuracy, durability and portability
in one practical design.
The memory accumulation feature keeps a running tally of each individual count – invaluable in batch counting operations or when accumulation counting large quantities of the same part.
