Rockwell Hardness Testers

 
FEATURES :

Akash Hardness Testers Models AIRAS, AIRASM, AIRAB-1, AIRAB-250, AI TWIN are manually operated. All these models are suitable for testing hardness of metals & alloys of all kinds hard or soft, whether flat, round or irregular in shape. These testers are simple in design & easy to operate, yet sensitive & accurate, various models from the wide range are suitable for schools, laboratories, toolroom, inspection departments, factories etc. These testers strictly conform to IS : 1586 - 2000, BS : 891 parts 1 & 2, ASTM: E 18 for Rockwell Test, IS: 2281 -1983, BS : 240, ASTM: E10 for Brinell Test & IS " 1586-2000, ASTM : E18 for Rockwell Superficial Test.

Manual load selection with automatic zero setting dial gauge. Manual Operation. Diamond Holder is guided in a set to two ball cage, which enables testing of small pins having dia. less than 6 mm. (upto 3mm dia.)

 
 
Principle :

Rockwell & Rockwell superficial tests consists of forcing an indentor (Diamond or Ball) into the surface of a test piece in two steps i.e. first with preliminary test force and thereafter with additional test force & then measuring depth of indentation after removal of additional test force(Remaining preliminary test force active) for measurement of hardness value.
