Digital Rockwell Hardness Testing Machines ( Model : TRS-DM, TSM-DM, TRB-DM, TRB-250-DM, TRS-DM-P )
This machine is designed for measuring hardness of metals & alloys of all kinds, hard or soft, whether round, flat or irregular in shapes.
Semi-automatic, motorized, digital, microprocessor based panel. We can get hardness in digital version.
Centronics parallel port for connecting dot matrix printer.
Three modes of operation viz.  Motorized automatic mode,  Motorized mode  & Manual mode.
Automatic weight selection by thumb wheel.
 
Test height x Throat is – 295 x 148 mm.
Machines strictly conforms to IS:1586 / 2281, BS: 240, ASTM-E-10
