Brief introduction: The hardness tester using rotary test force transformation mechanism and optical measurement system, on the body is equipped with the microscope measurement device. Because of low speed synchronous motor control automatic unloading test, the test force holding time can be achieved through delay potentiometer stepless adjustable, except the rockwell hardness test requirement artificial to dial zero, brinell hardness test and vickers hardness test respectively through a microscope measurement and the diameter of the indentation diagonal, no artificial operation error. Technical parameters: Rockwell scale: HRA, HRB, HRC HV100 vickers scale: HV30 Hardness reading: dial shows Hardness value for minimum resolution (HR) : 0.5 Test the force time: 1 ~ 30 s Specimen maximum height: 175 mm Head center to the fuselage distance (mm) : 145 mm Rockwell hardness test (70-85) HRA; (30-100); HRC HRB (20-67) Accuracy: value for + / - 1 hr Repeatability value: 0.8 HR Brinell hardness test: 8-650 HB Vickers hardness test: 14-1000 HV Light source: 5 v / 5 w Power supply: AC220V + 5%, 50 ~ 60 hz Size: 520 x240x700mm (length X width X height) Weight: 80 kg
