Elcometer Wet Powder Film Thickness Gauge

How to test wet and dry film thickness?

Excess coating negatively affects the longevity and the finish of the product

Too much of wet film can result in cracks when dry; too little film increases the risk of insufficient protection and rust spots. For powder coatings, the right thickness of applied powder is just as crucial: excessive powder means poor adhesion, and not enough – discoloration and less gloss.

Non-Contact Powder Thickness Measurement

The revolutionary Elcometer 550 correctly measures the final thickness of the applied powder before curing. It measures the density of the powder using non-contact ultrasonic technology and provides a predictive value of the cured coat.

Wet Film Combs


To measure the wet film thickness, touch the substrate with the comb’s teeth at 90 degrees angle and wait a few seconds. Remove the comb. The wet film thickness value is found between the biggest value ‘wet’ tooth and the smallest value ‘dry’ tooth.

Wet Film thickness gauge (wheel)


By rolling the wheel on the wet freshly coated surface, we apply the wet coating to the extremities of the disk. A scale placed along this edge indicates the thickness. The scales exist in a variety of measurements from 0 to 25µm – 0 to 3000µm (0 to 1mil – 0 to 40mils). When the correlation of solids vs volume ratio is known (usually indicated in the manufacturer’s datasheet), the Elcometer Wet Film thickness gauge can predict the dry film thickness.

Pfund Thickness Gauge

This gauge has two concentric cylinders one placed into another. A glass lens with measurements is placed within the central cylinder. When measuring, this spherical lens is pressed on the wet film. The mark is then measured and thickness indication is obtained using the supplied conversion table.
