Multi-Functional Scratch Tester features:
1. The instrument consists of the motor drive mechanism, scraping components, sample clamping fixtures and other components.
2. Scratch components include scraper brackets, scraping fingers, Scratches positioning sleeve, presses device (weights and weight support bars).
3. The instrument can be free to install, replace, disassemble different specifications of the scraping fingers. it also can impliments uniform speed unidirectional straight line scratch movement under different load .
4. The instrument that adopts embedded systems, man-machine interface operation automatically controls the test process . The use of precision servo motor, ball screw drive has a decisive role in controlling the scratch speed accuracy under the relevant standards .
5. The instrument uses tungsten carbide material to make scraping finger for increasing the instrument life.
6.The instrument which uses aluminum and stainless steel is appearance concisely、 lightweight and corrosion-resistant.
