Leeb Portable Hardness Testers

High precision hardness tester TKM459CE intended for quick measuring of metal Items hardness In laboratorlal, manufacturing and field conditions. The TKM-459CE works on the principle of "Ultrasonic Contact Impedance": The piezoelectric crystal causes the rod in the probe to vibrate longitudinally. The Vickers diamond at the lower end of the rod Is pressed by a spring Into the work piece surface. Depending on probe choice. this is done with the thrust of 10. 50 or 100 Newton.
