Product introduction

JB-4C precision roughness tester is a high-precision stylus-type surface roughness measuring instrument. The surface roughness is tested, and the shape, contour and other parameters of the surface roughness can be measured, and the TP steps of the workpiece can also be measured. The instrument is easy to use, with high measurement accuracy and stable repeatability.

The instrument is equipped with a computer and special measurement software, and uses an advanced noise-free mechanical positioning device, which can select different positions of the measured part, set various measurement lengths for automatic measurement, and the sampling data in the evaluation section reaches 3000 points. All measurement data and curves can be displayed on the screen or printed out, so it is widely used in various industries such as automobile supporting industry, machinery, mold processing, scientific research units, colleges and universities.

The instrument meets the requirements of national standards GB/T3505-2000, GB/T6062-2001, GB/T10610-1998, and international standards ISO5436 and ISO11562.
