Precision Roughness Tester

مقدمة المنتج

JB – 4 c precision roughness meter is a kind of high precision contact pin type surface roughness measuring instrument, the instrument can be on the plane, inclined plane, cylinder, inner hole surface, deep groove surface, circular arc surface and spherical parts surface roughness test, and implement the parameters such as the shape of the surface roughness and contour measurement, also can measure the workpiece TP steps (scratch).The instrument is easy to use, high precision and repeatability.

Equipped with computer and special measurement software, advanced noiseless mechanical positioning device, the instrument can select different positions of the parts to be tested, set various measuring lengths for automatic measurement, and the sampling data within the evaluation section can reach 3000 points.All measurement data and curves can be displayed on the screen or printed out, so it is widely used in automobile supporting industry, الآلات, mold processing, scientific research institutions, colleges and universities and other major industries.

The instrument conforms to the requirements of national standards GB/T3505-2000, GB/T6062-2001, GB/ T1010-1998, and international standards ISO5436 and ISO11562.
