Digital vickers hardness tester HVS-30
Features
New high-tech product integrating 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
Camera device can be connected via RS232 interface
Especially suitable for testing the hardness of micro and thin specimen, fragile material
Optional Knoop indenter can be used to measure Knoop hardness value
By means of closed-circuit system for control, CPU control testing force to load, dwell and unload, the sensor feedback information, therefore the lost of the testing force can be automatically compensated during testing for high accuracy.
