* 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.
* Manual or automatic shut down.
* Can memorize 7 groups of measurement results and measuring conditions for later use or download to PC.
* Metric /Imperial Conversion.
* Use USB/RS-232 data output to connect with PC.
* Provide data output choice.
Principle
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 inside the tester. The sensor gets the surface roughness 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..
