Rockwell hardness meter TRHM-A11 is a mechanical & electrical hardness testing instrument with novel design, digital display and micro-processor controlled loading system. Its automatic loading control eliminates operational errors in reading. It is used for the testing of ferrous & non-ferrous materials, plastic materials at Rockwell scale. The digital display shows test force values, dwell time, unloading, hardness results, conversion table etc. to study.
