Electric Superficial Rockwell Hardness Testing Machine
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.
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;
Precision conforms to GB/T230.1/.2 National Standard,ISO 6508-2,ASTM E18.
