The TQC Wet Film Thickness Gauge WG is a hexagonal/octagonal precision measuring comb made of heavy stainless steel. The high-grade stainless steel will not be affected by acid or base elements. Models available for several different applications.
Wet Film Thickness Gauges are designed to measure the thickness of coatings immediately after they have been applied to a substrate. The gauge has a series of notches cut into its sides like the teeth on a comb. The wet film thickness of coatings including paints, resins, lacquers, varnishes, and gels etc. can be measured.
- Place the gauge at a 90° angle to the coated substrate
- Make sure the gauge is in firm contact with the substrate.
- Remove the gauge in a straight line up.
- Assess the teeth of the gauge. The wet film thickness lies between the largest tooth that is wet and the smallest tooth that is not wet.
