HBRVS-187,5 Бринеллю цифровой и Рокуэлл и Vi

Model HBRVS-187.5 digital Brinell ,rockwell and vickers hardness tester has intuitive LCD d and microcomputer control system, so that hardness testing can be automately operated . The machine builted-in printer is to record the entire testing process of the main technical data. In addition to test hand-lift, the full realization of the test force imposing, removable, hardness value direct shows and other automated operation is achieved. The machine has high accuracy, eliminating the human operational error, is an integration of mechanical and electrical of high-tech and advanced hardness testing equipment. Therefore, the test machine with high precision, easy operation, high sensitivity, convinient use, reliable variable-Dutch, showing the stable value, is widely used in factory workshops, laboratories, universities and research institutions. Main technical parameters The preliminery Test Force (N): 98 Total Test Force Vickers hardness test (N): 294,588,980 Rockwell hardness test (N): 588, 980, 1471 Brinell hardness test (N): 306, 613, 1839 Microscope magnification: 37.5 ×, 75 × Hardness readings Indication mode: LCD Measuring eyepiece: Automatic Digital encoder Hardness Indication minimum division (HR): 0.1 Total test foce loading keeping time (s):1-60 Max height of test piece (mm): 180 (Rockwell) 135 (Vickers, Brinell) Depth of throat (mm): 140 Dimension (mm): 463 × 215 × 700 Supply Voltage: AC220V Source Voltage: 5V/5W Instrument Weight (kg): 75 Hardness test range Rockwell Hardness Test (70-85) HRA (30-100) HRB (20-67) HRC Indication Accuracy: ± 1HR Indication Repeatability: 0.8HR Brinell hardness Test (8-650) HB Indication accuracy (δ /%):± 2.5 shows the value of repeatability (Hcf /%): ≤ 3.0 Vickers hardness test (14-1000) HV Shows the value of precision (δ /%):± 2 shows the value of repeatability (Hcf /%): ≤ 2.5
