SRT-6210 Portable Digital Surface Roughness Tester USB RS-232 Data Output

This multi-parameter tester designed to measure 4 parameters (Ra, Rz, Rq, Rt) using the built-in Diamond pin probe. This tester is widely used in production site to measure surface roughness of various machinery-processed parts and calculate corresponding parameters according to selected measuring conditions and clearly display all measurement parameters in Metric or Imperial. It also have 4 wave filtering methods (RC, PC-RC, GAUSS & D-P) and memorize 7 groups of measurement results & conditions for for use at a later time.

Features:

• Multiple parameter measurement: Ra, Rz, Rq, Rt
• Highly sophisticated inductance sensor
