Digital Vickers Hardness Tester TH720/721
- Product Details
- Company Profile
● 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, indentation length, 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.
