main feature:
Lever loaded, manual operation, accurate and durable, high test efficiency; the dial can directly read HRN and HRT scales (other surface Rockwell scales can be selected); the accuracy meets GB/T230.2 ISO6508-2 and American ASTM E18 standards.
Applications:
Determination of the surface Rockwell hardness of ferrous metals, alloy steels, hard alloys and metals after nitriding, cyaniding, carburizing, electroplating, etc., after surface treatment; it is suitable for hardness testing of small parts and thin samples.
