Model:SRT-6210 1.FEATURES This instrument is compatible with four standards of site to measure surface roughness of various machinery-processed parts, calculate corresponding and clearly display all measurement parameters. * Multiple parameter measurement: Ra, Rz, Rq, Rt * Highly sophisticated inductance sensor * Four wave filtering methods : RC, PC-RC, GAUSS and D-P * Built-in lithium ion rechargeable battery and control circuit with high capacity * Small in size, light in weight and easy to use * Can communicate with PC computer for statistics, printing and analyzing by the optional cable and the software for RS232C interface. *Manual or automatic shut down. The tester can be switched off by pressing the Power key at any time. On the other hand, the tester will power itself off about 5 minutes after the last key operation. *The tester can memorize 7 groups of measurement results and measuring conditions for later use or download to PC. *Metric /Imperial Conversion 2.SPECIFICATIONS Display: 4 digits, 10 mm LCD, with blue backlight Parameters: Ra, Rz, Rq, Rt Measuring Range Ra, Rq: 0.005-16.00um/0.020-629.9uinch Rz,Rt: 0.020-160.0um/0.078-6299uinch Accuracy: Not more than ?0% Fluctuation of display value: Not more than 6% Sensor : Test Principle: Inductance type Radius of Probe Pin: 5um Material of Probe Pin: Diamond Dynamo-measurement of Probe: 4mN(0.4gf) Probe Angle: 90?
