• This machine is designed for measuring hardness of metals & alloys of all kinds, hard or soft, whether round, flat or irregular in shapes.
• This machine is ideally suitable for laboratories, tool rooms, Heat treatment shops, R&D departments, inspection departments, foundries & educational institutions.
• Automatic weight selection with automatic zero setting dial gauge.
• Rockwell test minor load is 10 kgf & major loads are 60,100,150 kgf.
• Rockwell hardness scales such as HRA, HRB, HRC, etc. is obtained by using different types of indentors
( Diamond / Ball ).
• Test height x Throat is – 215 x 132 mm
• Extra test height & throat of 295 x 148 mm, Model : MRS-150 is also available.
• Motorized versions are also available.
• Machines strictly conforms to IS:1586- 2000.
