MHB-3000 is a movable Brinell hardness tester. It adopts hydraulic principle and applies 3000Kgf test force by hand operation. The key part of MHB-3000 is a hydraulic system in which a release valve is used to control the test force. When the test force rises 3000kgf, the release valve will open and pressure will fall down, and it needs to apply the test force repeatedly 3-4 times to make the needle of the pressure gauge point to 3000kgf for 3-4 times. Thus, it is equivalent to the test condition of Brinell hardness testing method to hold 3000kgf test force with 10mm ball.
