FEATURES OF HARDNESS TESTER
   
Hardness Testers Models AI-RAS, AI-RASM, AI-RABI, AI-RAB250, AI-TWIN are manually operated. All these models are suitable for testing hardness of metals and alloys of all kinds hard or soft, whether flat, round or irregular. These are simple in design and easy to operate. Yet sensitive and accurate. Various models from the wide range are suitable for Eng Colleges, labs, Tool Rooms, Inspection Dept. These testers strictly conform to IS:1586-2000, BS:891 parts 1 & 2 ASTM: E18 for Rockwell Test IS:2281-1983, BS 240, ASTM E 10 for brinell Test and IS 1586-2000 ASTM E18 for Rockwell Superficial Test.
