LAB-H2compositeUltrasonic hardness tester

At present, there are many methods available for hardness testing, such asBrinell and Roche、Vickers、richter scaleUltrasoundwaveLaw, etc.among whichBrinell and Roche styleSignificant damage to the surface of the tested objectHowever, Vickers has higher costs and cannot test large workpieces；Leeb hardness tester is an indirect measurement of hardness, used to test Brinell and Rockwell hardness、The Vickers deviation is relatively large.With the development of microprocessorstechnological development, UltrasoundWave non-destructive testingMethod alreadyObtained industry recognition, among which ultrasonic thickness gauges and flaw detectors have been widely used, and ultrasonic hardness testers have also been popularized abroad.

LAB-H2ultrasoundPrinciple of Ultrasonic Hardness Tester

makehardness testerThe diamond indenter is in contact with the tested object, and under uniform contact pressure,probe headThe resonant frequency varies with hardnessdegreeBy measuring the change in frequency, the purpose of measuring hardness can be achieved. This method causes minimal damage to the tested object and has significant advantages compared to other methods mentioned above. based onabovePrinciple,Our company has introduced original European ultrasonic probes,Developed with high precision and strong functionalitybigofLAB-H2ultrasoundwaveHardness tester.
