The innovative horizontal design and footprint ensures stability on the bench top.

It is rugged enough for everyday use in the shop, yet designed for portability to take on the road.

The middle third of the gauge is the best range for testing and choosing your tester gauge option. Two pound increments on the 160 lb, and 10 lb increments on the rest. Extra Load Cell Modules can be purchased to have additional testing options.
