Portable Hydraulic Brinell Hardness Tester

Product Details :

PHB-3000 Hardness Tester adopts hydraulic principle and applies 3000kgf test force by hand operation. The central part of PHB-3000 is a small 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 for 10-15 seconds, which complies with ASTM E110.The accuracy and performance can reach the level of hydraulic King Brinell hardness teste
