Roughness Tester SRT-6200

Roughness tester features 1. SRT-6200
   Workpiece surface roughness measurement, the sensor on the surface of the workpiece measured, Roughness Tester SRT-6200 is driven by the drive mechanism of the instrument within the sensor do isokinetic glide along the surface to be measured, SRT-6200, roughness tester sensor through the built-in 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, thus generated in the output terminal of the phase-sensitive rectifier and the measured surface roughness than the column of the analog signal, the signal after amplification and level after conversion into the data acquisition system, the DSP chip will be data collected digital filtering and parameter calculation, measurement results are displayed on the liquid crystal display, SRT-6200 Roughness instrument can communicate with PC, data analysis and printing.
* Multi-parameter measurement: Ra.Rz.Rq.Rt;
* Precision inductive sensors;
* RC.PC-RC.GAUSS.D-P four filtering methods;
* Built-in lithium-ion rechargeable battery and charging control circuit, high capacity;
* Mechatronic design, small size, light weight, easy to use, built-in standard RS232 interface communicate with PC;
* Automatic shutdown function.
       This table has two shutdown: a manual shutdown, and another five minutes for keyboard operation shutdown.
* This table can memorize 7 groups of measurement data and measurement conditions to prepare for the next view or even the machine;
* Metric conversion function.
