Portable dynamic hardness tester TKM-359

Dynamic portable  hardness tester TKM-359

It is intended for measuring hardness of metal and alloy articles with Rockwell, Brinell, Vickers. It consists of the dynamic transducer (sensor) and the electronic module.

The principle of tester operation is based on determining velocity ratio of the indentor (the impact component with hard-alloy spherical tip) before and after striking the surface of the article being tested.

It has passed type approval testing. Certificate No. 23959. It is registered with the State Register of Measurement Means under No. 31764 - 06
