Accurate Stability Surface Roughness Tester , Handheld Roughness
Measure Instrument
SR210 / 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.
Key features:
320μm wide range high accuracy inductance probe;
Four filtering methods of RC, PC-RC, GAUSS and D-P;
Compatible with four standards of ISO, DIN, ANSI and JIS;
DSP chip is used to control and process data with high speed and
low power consumption;
Built-in lithium ion chargeable battery and control circuit;
Design of mechanical and electrical integration is adopted to
achieve small bulk, light weight and easy usage;
