Macro Vickers Hardness Tester TH720
|
|
·New high-tech product integrating mechanical and photoelectrical technologies
·Vickers hardness tester 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 |
