Touchstone™ 2 Coating Thickness Gauge


The TOUCHSTONE™ 2 coating thickness gauge is easy to use. Unlike the TOUCHSTONE™ 1, it requires no couplant, and will work on rough surfaces in any conditions.

Touchstone 2 Coating Thickness Gauge

The TOUCHSTONE™ 2 uses the magnetic properties of the substrate material to determine the coating thickness – ie, the distance that the sensor face is held of the steel by the coating.

  1. Calibrate the sensor by placing it on both the uncoated steel block AND the non-magnetic calibration block.
  2. Press the sensor firmly onto the coated surface and the thickness of the coating will be displayed.
