Surface Roughness Tester LSR220
Outline
The Surface Roughness Tester is a small handheld mobile measurement that suitable for production environment, research laboratory and factory measurement room. More importantly, it increases in the engine cylinder to measure the body surface platform-specific parameters reticulate, so it can be used in automotive, aviation, motorcycle ect. Simple operation, overall function, fast measurement, accuracy stability, convenience, it can measure the newest international standard the main parameter.
