Packing List

DR310 Surface Roughness Tester is applicable to the on-site production environment and meet the need of mobile measurement. With convenient operation, comprehensive functions, quick measurement, stable performance, it can measure all the main international parameters, which is in line with international quality standard, coming with varies of optional probe in different special use and measuring platform.

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.

4 parameters:Ra,Rq,Rz,Rt;

Employ electric-induction transducer with high precision;

4 filtering modes: RC, PC-RC, GAUSS and D-P;

4 Compatible standards:ISO, DIN, ANSI and JIS;

Segment LCD Display,simple and clear;

Adopts ARM chip for instrument controlling and data processing,with rapid computation speed;

Built-in lithium polymer rechargeable batteries and charging protection circuit;

Automatic switch off, memory and various prompt instructions;

Optional special probes and measurement platform.
