MMH-100 is a portable device which could be used for a vast range of metals in different industries. The small dimensions and the light weight of the tester have made it possible for the user to do the measurement while holding the instrument with one hand.
The device measures the hardness value of metals using the Leeb rebound test method. The device can convert the Leeb number into other hardness scales such as Brinell (HB), Vickers (HV), Rockwell C (HRC-C) and Rockwell B (HRB-B). The measurement and the calculations are done in less than one second. The device saves the minimum, maximum and average hardness values for 9 consecutive tests. The tester is equipped with an LCD display and rechargeable Li-Polymer batteries and is calibrated by the standard reference block which is provided as an accessory of the device itself. It is applicable for hardness measurement of a wide range of metals including cast steel, Cold Work Tool Steel, ductile cast iron, grey cast iron, aluminum, brass, and copper
