Coating Thickness Gauge is desgned to test :
- Thickness of paint & other dielectrics - radio absorbing , mastic, teflon, plastic, electroplating coating on steel.
- Thickness of galvanic & paint coatings on non-ferromagnetic alloys & non ferrous metals
- Thickness of bitumen & other  thick coatings on various metals & alloys
- As well as relative humidity, air temperature , surface temperature, dew point temperatue and differnece between surface & dew point temperature 
- Measuring grooves & surafce roughness .
