Digital Vickers Hardness Tester TH721
Description :Alat untuk uji kekuatan, panjang indentasi, nilai kekerasan, cocok untuk menguji kekerasan terhadap spesimen mikro dan, bahan rapuh
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
