Key words:portable roughness tester, roughness ra, surface
roughness, surface finish, roughness tester mitutoyo, roughness
testing machine, surface finish tester, surface roughness tester
manufacture, roughness testing machine manufacture
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.
