Surface Roughness / Finish Tester, Sanchi make 


The 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 surfaces is capable of evaluating surface textures with a variety of parameters according to various national standards and international standard. The measurement results are displayed digitall / graphically on the LCD, and output to the printer.


15 parameters : Ra, Rq, Rz, Rt, Rp, Rv, RS, RSm, Rz(JIS), RSk, R3z, Rmax, RPc, Rmr;High accuracy iductance pickup;Four filtering methods of RC, PC-RC, GAUSS and D-P;Compatible with four standards of ISO, DIN, ANSI and JIS;Can store 15 sets of measurements results 128 × 64 dot matrix LCD displays all parameters and graphs; DSP chip is used to control, and process data with high speed and low powerconsumption;Built-in lithium ion chargeable battery and control circuit have high capacity, without memory effect. Consecutive work time is longer than 20 hours;Design of mechanical and electical interation is adopted to achiever small bulk, light weight and easy usage;Can be connected to printer to print all parameters and graphs;Built-in standard RS232 interface enables communicaiton with PC;Automatic switch off, memory and various prompt instructions;Optional printer, analysis software and measurement platform.
