SURFACE ROUGHNESS TESTER
PCE-RT 10
This Surface Roughness Tester is small in
size, light in weight, easy to carry. Although
complex and advanced, it is convenient to
use and operate. Its ruggedness will allow
many years of use if proper operating
techniques are followed. Please read the
following instructions carefully and always

1. FEATURES
This instrument is compatible with four standard
f ISO, DIN, ANSI and JIS and is widely used i
o
p
roduction site to measure surface roughness o
v
arious machinery-processed parts, calculat
orresponding parameters according to selecte
c
m
easuring conditions and clearly display al
easurement parameters. When meas uring th
m
oughness of a surface, the sensor is pla ced o
r
t
he surface and then uniformly slides along th
urface by driving the mechanism inside th
s
ester. The sensor gets the surface roughness b
t
t
he sharp built-in probe. This roughness cause
isplacement of the probe which results in chang
d
o
f inductive amount of induction coils so as t
g
enerate analogue signal, which is in proportio
o the surface roughness at output end of phase-
t
sensitive rectifier. The exclusive DSP processe
