Digital Vickers Hardness Tester TH720/721
Feature
?New high-tech product with precise mechanical and photoelectrical technology
?Equipped with a digital microscope and cold light source, it shows the measuring method, test force, diagonal length of indentation, hardness value, dwell time and the times of measurement.
?Especially suitable for testing the hardness of small, thin and fragile material specimen
?Closed-loop control system:CPU control test force to load, dwell and unload, with high accurate pressure transducer sense feedback , the loss of test force automatically compensated.
