PHB-750 Magnetic Hydraulic Brinell Hardness Tester

PHB-750 Magnetic Hydraulic Brinell Hardness Tester
Fix the test head of hardness tester on the iron and steel part by the magnetic attractive force. The core part of this magnetic type Brinell tester is a small hydraulic system. The operator could actuate the hydraulic pump to produce 750kg test force by operating the pressure lever. There is a control valve in the hydraulic system which is used for controlling the test force. When the test force comes to 750kg, the control valve will immediately turn on and off, with the force falling down. According to the ASTM E110 and GB/T 4285, keep loading test force to make indicator hand points at 750kg for 3 to 4 times. It is an accurate and high qualified portable hardness tester for metal, and is equivalent to the regulation of Brinell hardness testing approach to hold test force for 10 to 15 seconds.

Features of PHB-750 Magnetic Hydraulic Brinell Hardness Tester

Design of magnetic type
1 Design of magnetic type Test can be finished as long as tester attached to one side of the specimen.
Test on site
2 Test on site The hardness test can be finished with no need for moving specimen.
Quality check after assembling
3 Quality check after assembling Used in the test for welded or assembled pipes, large-scale equipment and steel structure parts.
High reliability
4 High reliability A 5mm test ball and 750kg test force are applied in the test. Compared with the 2.5mm test ball condition, it has a larger indentation and better representativeness, and it is easier to read.
