MEWOI-SR300 Surface Roughness Meter Tester
INTRODUCTION
| MEWOI-SR300 Handheld roughness meter Suitable for cold rolling steel production sites, research laboratories and factory metering rooms.The hand-held roughness meter measures the surface roughness of a variety of machined parts, calculates the corresponding parameters according to the selected measurement conditions, and clearly displays all measurement results and graphics on the LCD display, and can be output on the printer. Communicate with the PC.With value storage and storage data query function. |
MAIN FEATURES
