The PosiTector SPG Certified Standards are traceable height standards mounted to a metal plate with calibration guide for recalibrating depth micrometer probes.

Testex Micrometer Analog Dial Thickness Gage Kits include everything required to measure the surface profile using replica tape.

Cleaning Cards for PosiTector RTR are pre-moistened with isopropyl alcohol to clean residual adhesive and debris from the anvils to insure an accurate test.

The PosiTector RTR Check Tape is used to check the operation of PosiTector RTR 3D peak density measurement (for use with the PosiTector RTR 3D only).
Replica tape for measuring blasted surface profiles. By placing the Tqc replica tape on the surface and rubbing over it, the Rt (total roughness) or peak-to-valley height of the profile can be taken and then measured with a film thickness meter.
1. TQC Replica tape consists of a layer of compressible foam affixed to an incompressible polyester substrate.
2.When pressed against a roughened/gritblasted (steel) surface, the foam collapses acquiring an impression of the surface.
3.Placing the compressed tape between the anvils of the SP1570 micrometric thickness gage, and subtracting the contribution of the incompressible substrate (50 micrometers or 0.002 inches), gives a measure of the surface profile.
One box of Testex contains tape for 50 measurements.
