Description
TH723/724 is a new digital heavy load vickers hardness tester. It adopts precise mechanical and photoelectrical technology. Closed-loop control system ensures the precision of the test force and the repeatability and stability of the measuring value. TH723/724 vickers hardness tester is suitable for testing ferrous metal, non-ferrous metals, coatings, ply-metals, glass, ceramics, agate, precious stones, thin plastic sections etc..
Feature
- New high-tech product with mechanical and photoelectrical technologies.
- Equipped with a digital microscope, direct display of the measuring method, test force, indentation length, hardness value, dwell time of test force.
- Especially suitable for testing the hardness of micro and thin specimen, fragile material.
- 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.
