Roughness Tester SRT-6210

Roughness tester features 1. SRT-6210
   Roughness Tester SRT-6210 using computer technology, in line with the national standard GB / T 6062 and ISO, DIN, ANSI and JIS four standard, SRT-6210 roughness instrument can be widely applied to the production site, SRT-6210 Roughness Tester measurable kinds of machined parts of the surface roughness, calculated according to the selected measurement conditions corresponding parameter SRT-6210 Roughness Tester LCD display clearly shows all the measurement parameters. SRT-6210 roughness measured workpiece surface roughness, the sensor on the workpiece measured surface roughness tester SRT-6210 is driven by the drive mechanism of the instrument within the sensor do isokinetic glide along the surface to be measured, SRT-6210 rough meter and sensors through the built-sharp stylus feel the measured surface roughness caused by the roughness of the workpiece surface to be measured, the stylus displacement, the displacement amount of the inductance of the inductance coil of the sensor changes, resulting in the phase-sensitive rectifier analog signal produced at the output with the measured surface roughness than the column, after the conversion of the signal after amplification and level into the data acquisition system, DSP chip will be collected data for digital filtering and parameter calculation, SRT-6210 roughness measured results displayed on the LCD display, and can communicate with PC, data analysis and printing.
