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.
