How to use the PosiTector RTR 3D?

Step 1: Preparation of both the surface to be tested and the PosiTector RTR H are necessary before performing the test.

PosiTector RTR Usage 01


To prepare surface:

To prepare the PosiTector RTR H:

Step 2: Burnish the Testex Press-O-Film™ replica tape onto the steel surface to form an impression/reverse replica.

PosiTector RTR H Usage 02

Testex Press-O-Film™ replica tape consists of a layer of compressible foam affixed to an incompressible polyester film of highly uniform thickness. When pressed against a roughened steel surface, the foam forms an impression, or reverse replica, of the surface.

 Step 3: Measure the Tape with the PosiTector RTR H

PosiTector RTR H Usage 03

Placing the compressed tape (replica) into the PosiTector RTR H 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 substrate from all measurements.
