Surface roughness meter RC-SRT01  RC-SRT02  RC-SRT01S  RC-SRT02S

Model:RC-SRT01    surface roughness tester
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

Model:RC-SRT02    surface roughness meter
1.FEATURES

This instrument is compatible with four standards of  ISO, DIN, ANSI and JIS and 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.

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.

* Very easy to operate

* 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

* Can communicate with PC computer for statistics,    printing and analysing 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.
