MET-MINIAll-in-one ultrasonic Hardness TesterNon-destructive portable hardness testing
The PHASE II all-in-one ultrasonic Hardness Tester MET-MINI is designed to measure the surface hardness of flat, round, thin or large surface workpieces on a wide range of metals.

MET-HRC, MET-HB and MET-HV meet ASTM A1038-10 specifications
Test Method:: MET-HRC, HB & HV Portable Ultrasonic Hardness Tester
"Ultrasonic Contact Impedance Method" This hardness test method is a hardness test method that obtains the hardness of the specimen based on the test of the change of the frequency of the resonant rod caused by the elastic properties of the limited contact surface itself during the process of pressing into the specimen. It is expressed as using a calibrated instrument to squeeze a resonant rod with a Vickers diamond indenter to the surface of the test specimen with a fixed force.
