MODEL PHB-3000 HYDRAULIC BRINELL HARDNESS TESTER

      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. 

Feature & Use

• On-site testing: It can be used in workshop, simple operation, easy carrying, and testing the hardness of large parts. It is convenient to test piece by piece.

• Permanent indentation: By 3000kgf and 10mm ball, the indentation is permanent for re-inspection.

• High reliability: It follows the Brinell hardness test method completely, the same as desk testers, reflecting the actual mechanical property of material or parts.

• Wide application range: As long as clamped to the parts, it could test parts in any shapes and sizes.

• Wide testing range: It could test various common metal materials by the combination of different test force, indenters and anvils, that is wide testing range.
