Surface Roughness Tester Portable, roughness measuring instrument, Ra Rz SRT150
Product Description
The Surface Roughness Tester is widely used in production site to measure surface roughness of
various machinery-processed parts, calculate corresponding parameters according to selected
measuring conditions and clearly display all measurement parameters.
Product Feature
* Be compatible with four standards of ISO, DIN, ANSI and JIS. 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.
* Multiple parameter measurement: Ra, Rz, .
* Highly sophisticated inductance sensor.
* 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.
* Metric /Imperial Conversion.
* Use USB data output with connection PC.
* Provide Bluetooth data output choice.
