Product Specification Parameter HB Display Type Analog Model Name/Number PHB-3000 Dimension 350mm (Height) x 100mm(Throat depth) Automation Grade Manual Weight 14 kg approx Hardness Scale HBW Test Range 32-650HBW Test Force 3000kg (1000kg,750kg,500kg optional) Diameter 10mm ball Load Capacity 3000 kgf Minimum Order Quantity 1 Product DescriptionWorking 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
