Touchstone™ 2 Coating Thickness Gauge

Overview of the Touchstone 2

The Touchstone 2 coating thickness gauge is easy to use and requires no couplant, it will work on rough surfaces in any condition.

This coating gauge uses the magnetic properties of the substrate material to determine the coating thickness – ie the distance the sensor face is held off the steel by the coating. The Touchstone 2 Hall effect sensor will measure a wide range of non-magnetic coatings on ferrous substrates including;

  • paint, plastic, stainless steel, galvanised zinc, aluminium and tin
  • Highly accurate Hall effect sensor
  • Measures any non-ferrous coating
  • Measures up to 8mm of coating
  • Simple calibration and operation
