Press-O-Film Replica Tape
Press-O-Film provides a simple way to obtain an impression of
a surface for analysis. It consists of a layer of crushable plastic
micro foam affixed to a 50.8 µm (2 mil) incompressible polyester
film. When compressed against a roughened surface, the foam
collapses and acquires an accurate impression, or reverse
replica, of the surface. It is available in
Coarse (C) and X-Coarse (XC) grades
to accommodate measurements in
different profile ranges.
Placing the compressed tape (replica) into the PosiTector
RTR
gives a measure of the average maximum peak-to-valley height
of the surface roughness profile. The Gage automatically subtracts
the thickness of the polyester film from all measurements.
Probes
When powered-up, the PosiTector automatically
determines which probe is attached and does a self-
check.
To disconnect a probe from a body, slide the plastic
probe connector horizontally (in the direction of the
arrow) away from the body. Reverse these steps to
attach a different probe. It is not necessary to power-
down the Gage when switching probes.
The PosiTector gage body accepts a wide variety of
probe types including magnetic, eddy-current and
ultrasonic coating thickness, surface profile,
environmental, hardness, salt contamination and
ultrasonic wall thickness probes. See
