Product Description

DRT P4 Surface Roughness Tester is a pocket-size tester, which is convenient to bring with and easy to operate. It can not only test flat surface, ex-circled surface with dia.>20mm,conical surface, but also groove with minimum side of 80x30mm.

Model DRT P4 is defined a standard type, supporting four parameters, with high accuracy and good value for money.

Measuring principle

When measuring roughness on specimen surface, the probe is placed on the surface of the specimen, and then tracing the surface at constant rate. The probe acquires the surface roughness by the sharp stylus inside. The roughness on surface causes displacement of stylus which results in change of inductive value in induction coils, thus generates analogue signal which is in proportion to the tested surface roughness at the output end of phase-sensitive rectifier. This signal enters data collection system after amplification and level conversion. After that, those collected data are processed with digital filtering and parameter calculation by DSP chip and the measuring result can be read on LCD, or printed out through printer or communicated through PC.
