BRV187.5 Universal (Brinell Rockwell Vickers) Hardness Tester is a multifunctional hardness testing equipment, it can test the hardness by brinell, rockwell, vickers three test ways.
It has multilevel test force, can meet different test requirement. It has high test accuracy, simple operation and stable indication.
Features:
● 3 types including Brinell, Rockwell, Vickers three kinds of test methods
● 7 level of force, multi-function, can satisfy user’s multi-purpose requirements
● Rockwell reading in dial pointer, Brinell/Vickers lookup in table
● Automatic loading and unloading of test force
● Wide utilization, convenient operation
Application:
● Widely used in the Rockwell, Brinell, and Vickers hardness test of Ferrous and nonferrous metals
● Castings, annealed steel, normalized steel, non-ferrous metals and soft alloys ( Brinell )
● Heat-treated materials ( Rockwell )
● Nitriding layer, ceramic, sheet, foil, plated layer, and minute parts ( Vickers )
