SRT-6450 Handheld Digital Display Surface Roughness Meter
1.Product Overview
This surface roughness measuring instrument is a handheld device suitable for production site environments and mobile measurement needs. It can measure the surface roughness of various machined parts, calculate the corresponding parameters based on the selected measurement conditions, and display all measurement parameters and contour graphics on the display. This instrument can measure the main parameters of the latest international standards and fully and strictly adheres to international standards. The measurement parameters comply with the national standard GB/T3505 "Product Geometric Technical Specifications - Terminology, Definitions and Surface Structure Parameters of Surface Structure Contour Method" and are compatible with the standards of the United States, Germany, Japan, the United Kingdom and other countries. It is applicable to various machined parts, mechanical processing manufacturing industries, inspection, commodity inspection and other departments, especially suitable for on-site inspection of large workpieces and production lines, as well as external verification by inspection, metrology, commodity inspection and other departments, without causing damage to the workpieces.
Measurable workpiece range: plane, outer circular surface, conical surface, inner hole, groove, curved surface, etc. (Special surfaces need to be measured with suitable sensors).
