Introduction: This model of micro Vickers hardness tester is designed and produced according to the standards of GB/T4340.2-2012, ISO6507-2 and ASTME384 of the United States. It is a new type of hardness testing instrument that combines mechanical, optical and computer technology. It can automatically switch the objective lens, Indenter, input the measured diagonal length value, automatically perform hardness calculation, storage, display, printing and hardness conversion functions. It is suitable for testing the Vickers or Knoop hardness of tiny metal parts, thin sheets, metal foils, hardened layers, electroplated layers, nitride layers, carburized layers, and cyanide layers. It can also be used for jewellery, ceramics and glass. Non-metallic materials that cannot be tested by the test force. This instrument has the characteristics of accurate test accuracy, high reliability, comprehensive intelligence, minimal indentation, and no damage to the sample. This machine can be used as a metallographic microscope to observe the structure and body of the material. When the interface is matched with the computer, the CCD camera and software card can be installed to be used as a microhardness tester for image processing. Its powerful functions are relatively current. Ideal testing instrument. The experimental results and images can be transmitted through the network. technical parameter: Vickers scale: HV0.01, HV0.025, HV0.05, HV0.1, HV0.2, HV0.3, HV0.5, HV1 Test force: 0.098, 0.2542, 0.4903, 0.9807, 1.961, 2.942, 4.904, 9.807 (N) 10 25 50 100 200 300 500 1000 (gf) Test force selection: Select the test force by turning the test force conversion handwheel, and the current test force is displayed on the screen Loading control: automatic (loading/holding/unloading) Turret: automatic turret Dwelling time: adjustable from 1 to 60 seconds (5 seconds in increments) Test mode: HV/HK Hardness value range: 5-3000HV, through the data measured on the micrometer, input the data into the hardness tester to get To the corresponding hardness value.
