Description
Model:SRT***0
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 RS**2C 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.
