A stack light and audible alarm alert you when packages, products, and parts are too heavy or too light. Also known as check weighers, these scales verify quality and consistency in packing, parts machining, and other activities. Set your weight range, and the stack light tells you if an object is OK to go using three colored lights: one for too heavy, one for too light, and one for just right. Specific measurements appear on a bright, backlit LCD.

The scale's memory stores up to 10 weight ranges, so you can switch from one range to another as your tasks change. In counting mode, the scale tallies the total number of parts based on the weight of a single part. When using a container to hold small items, press the tare button to reset the scale to zero. To print or transfer data to a computer, connect an RS-232 computer cord (not included) to the scale's DB9 port.

Safely weigh material in hazardous environments—these scales operate with low voltages so they won’t create sparks. They’re FM approved and also comply with NEC standards for use in Class I, Division 1, Group C and D environments, so they can be used where flammable gases, vapors, and liquids with characteristics similar to propane and ethylene can be found under normal operating conditions.

These scales are among the most accurate bench-top scales we offer, so you don’t have to compromise precision for safety. They have several different modes: check weighing notifies you if an item falls outside of a certain weight range, counting keeps tally as you add or remove pieces, and the tare function resets the scale to zero after placing a container on the platform. A backlit LCD display lets you easily read out measurements in low lighting.

Scales run for 200 hours on four AA batteries (sold separately). Use a carrying case (sold separately) for secure transport.

Count and weigh loads that are difficult to lift. The weighing function is NTEP approved for use with products sold by weight. Scales have a tare function that lets you reset the scale to zero after placing a container on the platform. Scales operate on the included AC adapter or batteries (not included).

To quickly check inventory, roll these dollies wherever you need them to weigh and count the contents of drums. Their built-in scale measures weight and has an accurate piece-count mode—even while adding or removing contents from your drum. Dollies have three sensors for reliable readings on uneven floors. For loading heavy drums, they have a low-profile platform. The scale has a rechargeable battery with a USB charging cable.
