PHR Series Portable Rockwell Hardness Tester - Manual type. The PHR is a range of handheld, manual Rockwell type metal hardness testers.

The PHR is lightweight, compact and easy to operate, meaning it can be used anytime, almost anywhere. Initial testing force is 10kg, and main testing force is 60kg, 100kg or 150kg depending on the measuring scale - just like a bench-mounted unit. Force is applied by diamond (Rockwell A, C) or carbide ball indenter (Rockwell B) and screw so that the indentation is small.

It is often used in non-destructive testing to test the sample directly without the need for removal. It can not only test standard samples, hardware and tool parts, but also can test the inconvenient parts which are not suitable for testing with LEEB rebound type and bench hardness tester to test. Measurement accuracy meets standard GB/T230, ASTM E18.

This kind of tester is suitable for testing finished or semi-finished batching processed samples one by one. It can be used for production site, sales site and material warehouse.

Application: All common metals, including steel, copper, aluminum, nickel, lead, tin, cemented steel, hard alloy, etc.
