main features
main features
1. Simultaneously equipped with Vickers and Knoop indenters, as well as high magnification (40X/50X) and low magnification objective lenses (10X/20X);
2. During testing, the pressure head and objective lens automatically switch to each other, and the testing point is automatically positioned accurately;
3. Adopting an optical cross rail guided lifting mechanism to ensure guiding accuracy; Adopting gear rack two-stage force transmission can achieve fast and smooth force transmission;
4. The light source uses LED lights, which have a long lifespan and do not require bulb replacement;
5. Can be equipped with a built-in camera for clearer images.
6. Calibration can be carried out according to standard hardness blocks or length scales, and hardness correction can be automatically performed based on high, medium, and low hardness values, resulting in more accurate hardness values..
7. 8-inch touch screen interface, user-friendly operation;
8. All experimental parameters and results are stored in Excel format on a USB drive for easy data processing and inspection report output;
9. Conversion of various hardness values;
10. The experimental setting parameters are password protected;
11. At least three languages, including Chinese and English, are available for selection;
12. Equipped with RS-232 interface, it can be connected to a computer;
13. Optional maximum test force of 2kg.
