These Electronic Spring Testers are highly configurable motorized test stands for tension and compression testing applications up to 300 lb (1.5 kN). The stands can be controlled from the front panel or via computer.
The Electronic Spring Testers are engineered on a unique modular platform, allowing for "build-your-own" configurability. Features can be ordered individually at time of order or activated in the field. Integrated travel indication, overload protection, and a host of programmable parameters makes the ESM301/ESM301L quite sophisticated, while its intuitive menu structure allows for quick, simple setup and operation. A password can be programmed to prevent unauthorized changes. With a rugged and modular design, the test stand is a compelling solution for applications in laboratory and production environments.

The ESM301 travel distance is 11.5", while the extended length ESM301L features travel distance of 18". All other specifications are the same.
