SAROJ Hardness Testers Model RAS, RAB-1,
RAB-250, 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 shape. These testers are
simple in design and easy to operate,
yet sensitive & accurate. Various models
from the wide range are suitable for
schools, laboratories, tool-rooms,
inspection, heat treatment departments,
factories etc. These testers strictly
conform to IS : 3804 -1988, BS : 891
parts 1 & 2, ASTM : E 18 for Rockwell
test, IS : 2281 -1983, BS : 240, ASTM :
E 10 for Brinell test and IS 5073 -1988
ASTM : E 18 for Rockwell Superficial
