Description:
The hand-held roughness tester is a new product. This tester applies to production site and can be used to measure surface roughness of various machinery-processed parts, calculate parameters according to selected measuring conditions and clearly display all measurement parameters and profile graphs on LCD.

Features:
1.Multi-parameter measuring: Ra, Rz, Ry, Rq, Rp, Rm, Rt, R3y,R3z, Rmax, Rsk, Rku, S, Sm, tp, Rmr, Rpc, RzJIS;
2.High accuracy inductance sensor;
3.Four filtering methods of RC, PC-RC, GAUSS and D-P;
4.Compatible with four standards of ISO, DIN, ANSI and JIS;
5.128×64 dot matrix LCD displays all parameters and graphs
