This digital automatic turret microhardness tester is a new generation of multi-functional touch screen microhardness tester developed by our company. The tester has a novel design and features excellent reliability, operability and repeatability, making it an ideal product for microhardness testing. The machine is programmed in C language and equipped with a high-magnification optical measurement system and an optical dual-channel structure. It also adopts new technologies such as photoelectric and photoelectric coupling sensors, which can meet the basic requirements of Vickers hardness testing and quickly and accurately obtain measurement values. The upgraded control operating system is equipped with a 7-inch LCD touch screen, which can provide more measurement data.
Main uses and application scope:
1. Steel, non-ferrous metals, metal foils, hard alloys, metal thin plates, microstructure
2. Carburized, nitrided and decarburized layers, surface hardened layers, electroplated layers, coatings
3. Glass, wafers
