HBRV-187.5 Universal Hardness Tester

Model: HBRVT-187.5B

Universal Hardness Tester has Rockwell, Vickers and Brinell testing capability. 
HBRV-187.5 Motorized Brinell Rockwell & Vickers Hardness Tester enables the execution of Rockwell standard (150-60-100kgf), Brinell (31.25-62.5-187.5kgf) and Vickers tests (10-30-60-100kgf).  

This test is suitable to determine the Brinell, Rockwell and Vickers hardness of ferrous, non-ferrous metal and hard alloy. Dial display the Rockwell hardness scale; check Brinell and Vicker’s hardness through microscope; It's steady and reliable for testing of curved surface.
