• 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
