Portable surface roughness meter GR120 parameters is in accordance with GB/T 3505-2000(the geometrical product specification, surface contours, surface structure predication, definition and parameters), in line with the GB/T 6062-2002(the product geometry specification (GPS) surface structure, contour method, contact (needle) nominal characteristics of the instrument).
Application scope: metal and nonmetal parts surface roughness detection. Applicable to a variety of machining parts, mechanical processing, manufacturing, inspection, commodity inspection departments, especially applicable to large workpiece and the field inspection on the production line, outer verification of the detection, measurement, commodity inspection departments. It will not have damage on the workpiece. Measurable work-piece range: plane, cylindrical surface, conical surface, inner hole, groove and curved surface, and other special surface (with applicable sensor).
Unique features: pass strict temperature&humidity test, adapt to high temperature and high humidity working environment, measurements are not affected even in extreme humid climate. High precision, stable measured value, China's leading quality!
