The performance advantage:
1.The roughness of metal and non-metallic surface
2.Pocket-size & economically price
3.Large measuring range suitable for most materials
4.Features external calibration at keyboard
5.Optimized electric circuit design with transducer structure-design,high integrate power, driver and display.
6.Select freely with Ra,Rz, Rq, Rt parameters.
7.It could test ex-circle, flat surface, conical surface and also test groove with length and width larger than80*30mm.
