ROCKWELL CUM BRINELL HARDNESS TESTERS
ROCKWELL CUM BRINELL HARDNESS TESTING MACHINES
( Model: MRB, MRB-250 )

 
ROCKWELL CUM BRINELL HARDNESS TESTERS
 
• Rockwell Cum Brinell Hardness Testing Machine used to measure hardness of metals & alloys of all kinds, hard or soft,    whether round, flat or irregular in shapes.
• Rockwell Cum Brinell Hardness Testing Machine is ideally suitable for laboratories, tool rooms, Heat treatment shops, R&D    departments, inspection departments, casting & forging industries, educational institutions.
• Rockwell & Brinell method is used for checking hardness on metals & alloys of all kinds.
• Brinell hardness is also checked on non-ferrous materials like Cast iron, Alluminium, etc.
• Automatic weight selection with automatic zero setting dial gauge.
• Rockwell test minor load is 10 kgf & major loads  are  60,100,150 kgf. Brinell test for Model : MRB major load is 187.5  & for    Model : MRB-250 are   187.5, 250 kgf.
• Rockwell hardness scales such as  HRA, HRB, HRC, etc. Brinell hardness scale such as HB is obtained by using different types    of indentors ( Diamond / Ball ).
• For  Model : MRB,  Test height x Throat is – 215 x 132 mm. For  Model : MRB-250,  Test height x Throat is – 295 x 148 mm.
• Motorized versions are also available.
• Machines strictly conforms to IS:1586- 2000 for Rockwell test, IS:2281, BS:240, ASTM-E-10 for Brinell test.
