Electric Superficial Rockwell Hardness Testing Machine

Electric Superficial Rockwell Hardness Testing Machine

Application:

Determine the superficial hardness of ferrous metals, alloy steel, carbide and metal after nitriding, cyanidation, carburizing, electroplating and other surface treatment;

It is suitable for the hardness test of small parts and thin samples.

Main Features:

Manual superficial hardness tester HR45A has stable and reliable performance , it is economical type without electric power supply;

The dial reads the hardness value directly, indicator responses sensitively, show the hardness value accurately, the test value is more accurate than national standard;

Direct dial readings,with scales of HRN,HRT(other Rockwell scale optional) ;

Onetime casted molding shell, stable structure and it is not easy to be out of shape. It can work under harsh environment;
