Metal Analog Portable Hydraulic Brinell Hardness Tester, Model Name/Number: THB-3000

Working Principal :Fix the test head of Brinell hardness tester to the test frame.When testing, fix the measuring frame onto the surface of the test piece firmly, load force by operating the handle. The test head is a mini hydraulic system which contains a control valve for controlling force. When force loading to 3,000Kgf,the control valve opens,pressure releasing. According to ASTM standard, force loading should be repeated 3 to 4times, keeping the pin of the pressure gauge reaching the point of 3,000Kgf 3 to 4 times. ln this way, it equals the test regulation of test force 3,000 Kgf, iDmmtest ball, force maintaining time; 0 to 5 seconds
