Product Code : SRT-6210
Brand Name : SURFACE TESTER
Product Description

We have established a strong market foothold by manufacturing and supplying an exclusive range of Surface Roughness Tester. These testers are ideal to test the roughness of different machinery-processed parts in real time application. To comply with the latest technology, we use best quality components and materials sourced from the most reliable vendors to manufacture the tester. Our Surface Roughness Tester is equipped with built-in lithium ion rechargeable battery and control circuit with high capacity. We offer the tester at pocket friendly prices.

Features:

  • Accurate measurement

  • Small in size

  • Light weight

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.

When measuring the roughness of a surface, the sensor is placed on the surface and then uniformly slides along the surface by driving the mechanism by the sharp built-in probe. This roughness causes displacement of the probe which results in change of inductive amount of induction coils so as to generate

analogue signal, which is in proportion to the surface roughness at output end of phase-sensitive rectifier. The exclusive DSP processes and calculates and then

outputs the measurement results on LCD.

* 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
