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
