Main Function:
RH-300L Digital Rockwell hardness tester is equipped with a newly-designed large displaying screen with good reliability, excellent operation and easy watching, thus it is a high-tech product combining the
mechanic and electric features. It can show and set the present scale, test force, test indenter, dwell time and hardness conversion; the main function is as follows: Selection of all the Rockwell scales; Conversion scales of different kinds of hardness; Test results can be saved and printed out, automatic calculation of maximum, minimum and average value; With RS232 interface for connecting to the computer. This is the heightening type which is more convenient for measuring the large samples.
Application range:
Suitable for quenched steel, tempered steel, annealed steel, cold and hard casting, malleable cast iron,
hard alloy steel, aluminum alloy, copper alloy, bearing steel etc.
