Coating Thickness Gauges
Introduction
Coatings are materials that are applied to a surface to improve its appearance, performance or durability. Coatings can be applied to a variety of materials, including metal, wood, plastic, and concrete etc.
There are many different types of coatings, most common types include Polyurethane coatings, Epoxy coatings, Alkyd coatings, Zinc coatings, Acrylic coatings etc.
Coating thickness gauges provides accurate measurement of the thickness of coatings over coated substrates. Coating thickness gauges play a very crucial role in quality control processes, enabling manufacturers to verify coating thickness during production to ensure consistency in product performance. Correct measurement of coating thickness using these gauges detects surface defects such as uneven coatings, inadequate coverage, or insufficient adhesion, and also ensure longevity and durability of the coated substrates by monitoring coating thickness over time, by detecting changes in thickness they help to classify areas prone to corrosion.
Coating thickness measurement core working principles: Magnetic Induction and Eddy Current.
Magnetic Induction: This principle involves using a probe with a magnetic field that interacts with the substrate and coating. The gauge measures the change in magnetic field strength, which correlates to the coating thickness.
Eddy Current: A probe emits an alternating current that creates a magnetic field. When the probe is placed near a conductive coating, eddy currents are induced. The gauge measures the changes in these currents, providing information about the coating thickness.

Wet Film Thickness Gauge
Hexagon Type (25–3000 µ)
Introduction
Coatings are often used for barriers over various substrates such as spray polyurethane foam, wood, I-joist and gypsum, steels etc. When applying a coating to any substrate, the thickness of the coating is extremely important and needs to be measured and recorded accurately. Wet film thickness, or WFT, is the measured thickness of any liquid applied coating to surface while it is still wet. Dry film thickness, or DFT is a measurement of the dry and cured material after all liquid has evaporated.
DFT = WFT × % volume solids. For a 50% volume solids material with a WFT of 20 mils, DFT = 20 × 0.50 = 10 mils DFT.
Measuring the WFT of a coating enables the applicator to adjust the spray gun speed, number of sprays passes and to make spray gun adjustments to ensure sufficient coating is applied to cover complete surface and targeted DFT is achieved.
Place the Wet Film Gauge Perpendicular on wet coated substrate,
gauge both end edges must adhere firmly to the substrate.
Remove the gauge and note the Tooth which is wet and adjoining tooth that is dry, the reading is in between these two teeth.
In above E.g. as marked, the 4mm tooth is wet and 6mm tooth is dry. So the wet film thickness is greater than 4mm and less than 6mm.
