Manual Rockwell hardness tester, mechanical dial hardness testing machine

HR-150AManual Rockwell hardness tester, mechanical dial hardness testing machineProduct Introduction:

1. Adopting mechanical manual testing, no need for power supply, wide applicability, easy operation, good economy and practicality;

2. The body is made of high-quality cast iron and cast in one go, combined with automotive paint treatment technology, with a round and beautiful appearance;

3. The dial directly reads the hardness value and can be optionally equipped with other Rockwell hardness scales such as HRD, HRF, etc;

4. Adopting a frictionless spindle, the test force accuracy is high;

5. The precision hydraulic buffer adopts integrated casting, with no buffer liquid leakage, smooth loading and unloading, no impact, and adjustable speed;

6. The accuracy complies with GB/T230.2-2018, ISO6508-2, and ASTM E18 standards in the United States.

Application scope:

1. Measure the Rockwell hardness of ferrous, non-ferrous, and non-metallic materials;

2. Measurement of Rockwell hardness of heat-treated materials such as hard alloys, carburizing steel, quenched steel, surface quenched steel, hard cast steel, aluminum alloys, copper alloys, malleable castings, soft steel, quenched and tempered steel, annealed steel, bearings, etc.
