Description
TH720/721 is a powerful digital vickers hardness testing machine with closed-loop control system. The measurement is extremely easy and accurate.
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, 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.
