Rockwell hardness meter TRHM-A10

Rockwell hardness meter TRHM-A10 is used for the testing of ferrous & non-ferrous materials at Rockwell scale. The high quality stainless steel used in its preparation assures reliability & durability of the hardness tester. With novel appearance its analogue gauge display the hardness indication with good resolution. Equipped with oil pump controls test operations, it reduces operator’s involvement.
