Product name: Surface Roughness Tester SADT SR220

Views:

Goods ID: 15485189

  • Introduction
  • Parameter
  • SR220 portable surfaces roughness tester is a small handheld instrument with big LCD, high accuracy and various parameters. It can be used in the laboratory, inspection area or wherever on-site surface roughness testing is required. The measuring data of SR220 can be output to PC or micro printer.
