Portable roughness Tester is a portable stylus surface roughness shape measuring instrument, which is suitable for the detection of workshop verification stations, laboratories, measurement rooms and other environments. The measurement parameters are in line with international standards and compatible with the standards of some industrially developed countries such as the United States, Germany, Japan, and the United Kingdom. The measurement results can be displayed digitally and graphically on the LCD display or output to a printer.

It is suitable for processing industry, manufacturing, testing, commodity inspection and other departments, mainly suitable for on-site inspection of large workpieces and production lines, as well as out-of-office verification of testing, measurement, commodity inspection and other departments.
When measuring the surface roughness of the workpiece, the instrument first puts the sensor on the measured surface of the workpiece, and then starts the instrument to measure, the precision driving mechanism inside the instrument drives the sensor to do a straight line along the measured surface at equal velocity, the sensor feels the roughness of the measured surface through the built-in sharp contact pin, and the roughness of the measured surface of the workpiece will cause the displacement of the stylus, and the displacement changes the inductance of the sensor inductance coil, so as to generate an analog signal proportional to the measured surface roughness at the output end of the phase-sensitive Detector, and the signal enters the data acquisition system, DS after amplification and level conversionThe P-chip digitally filters and calculates the parameters of the acquired data, and the measurement results are given on a monitor, can also be output on a printer, and can also communicate with a PC.
