HR-45A Manual Superficial Rockwell Hardness Tester
HR-45A Manual Superficial Rockwell Hardness Tester suitable for measuring superficial rockwell hardness of Ferrous Metals, Alloy Steel, Carbide and Metal after treated surface (carburizing, nitriding, plating layer). Especially suitable for precision measurement of Parallel Planes.
It mainly functions are as follows:
1.1. Lever Loading, manual operation, durable and reliable.
1.2. No friction spindle, high precision test force.
1.3. Precision hydraulic buffers, steady load.
1.4. Dial display the hardness value, HRN, HRT, and can choose other Rockwell Scale.
1.5. Accuracy according to GB / T230.2, ISO 6508-2 and American ASTM E18 standard.
