SRT-200 Surface
Roughness Tester
Description:
The SRT-200
surfaces roughness measure instrument is suitable for shop floor use and mobile
measure to need of a small handheld instrument, it operation simple, function
overall, measure fast, accuracy stability, take convenience. The SRT-200 is
capable of evaluating surface textures with a variety of parameters according
to various national standards and international standard. The measurement
results are displayed digital/ graphically on the LCD, and output to the
printer.
Features:
◆ 15parameters: Ra, Rq, Rz, Rt, Rp, Rv, RS RSm,
Rz(JIS), Ry(JIS)
,RSk,R3z,Rmax, RPc, Rmr;
◆ High accuracy inductance pickup;
◆ Four filtering methods of RC, PC-RC, GAUSS and D-P;
◆ Compatible with four standards of ISO, DIN, ANSI and JIS;
