China Rockwell Superficial Rockwell Hardness Tester

Rockwell/Superficial Rockwell Hardness Tester
Model No. : RH-450 Rockwell
Model No. : RH-550 Superficial Rockwell
RH-450 can be used directly to measure Rockwell hardness and plastic Rockwell hardness, and it can change the value of Rockwell hardness into HB, HV, HLD, HK and σb value.
RH-550 can be used directly to measure Rockwell Superficial hardness and plastic hardness, and
it can change the value of Rockwell superficial hardness such as HR15N, HR30N, HR 45N, HR15T,
HR30T and HR45T scale into HV, HB, σb and HK value.
