1. Measuring range: 5-650HBW 2. Test force selection: 30,31.5,62.5,100,125,187.5,250,500,750,1000,1500,2000,2500,3000kgf 3. Maximum allowable height of the sample: 230mm 4. The distance from the center of the indenter to the machine wall is 165mm 5. Hardness value resolution: 0.1 6. Touch screen size: 8 inches 7. Dimensions: 700*268*842mm; 8. Power supply: 220V, 50HZ1. Using 8-inch color touch screen, display information is rich, user operation is convenient and intuitive. 2. The fuselage adopts the casting process, which strengthens the stability, reduces the influence of the frame deformation on the hardness value, and improves the test accuracy. 3. Automatic turret, automatic switching between indenter and lens, more convenient to use 4. Can be converted to each other through the measured hardness values of each scale; 5. The electronic closed-loop control applies the test force, and the force sensor controls the test force with an accuracy of 5‰, and fully realizes the automatic operation of the application, maintenance and removal of the test force; 6. The fuselage is equipped with a microscope, and is equipped with a 20X, 40X high-definition microscope optical system to make the observation and reading clearer and reduce errors; 7. Equipped with a built-in micro-printer, and an optional RS232 data cable can be connected to the computer through a hyper terminal to export the measurement report
