New! Economic Portable Hardness Tester

portable hardness testers pht-1700

Model No. PHT-1700

Loaded with features, this economically priced portable hardness tester is capable of measuring the surface hardness of a broad variety of metals on flat and round surfaces. This portable hardness tester comes complete with the universal D impact device, calibrated test block and rugged carry case.

The PHT-1700 Portable Hardness Tester can perform tests that easily convert to the most popular hardness scales including Rockwell, Brinell, Vickers, Shore, etc.

Designed to test large hard parts:

Example: Tool steel should be close to 1” thick of solid material
