Universal hardness tester TH-174
Quick and easy
The hardness testers of the TH-series are especially suitable for quick and easy hardness measurements.
They are applicable with almost all hardness measurements on ferrous and non- ferrous metals. Costumers of the product include the power industry, petrochemical industry, apparatus-, automotive- and mechanical-engineering, quality control, steelworks and many more.

Application
Fixtures, dies, molds, large parts, narrow spaces, axles, steering knuckles, frames, etc. Furthermore the device is often used for material identification, and for error checking in pressure vessels and steam turbines. The great advantage of the TH-174 is the availability of getrting to narrow, very difficult to reach parts.
