The Rulina-type wet film thickness gauge enables the precise measurement of the thickness of freshly applied coatings. Made from stainless steel, it consists of an eccentric central disc surrounded by two knurled concentric side discs.
When rolled over the coated surface, the central disc comes into contact with the wet film at a specific point, which corresponds to the thickness value indicated on the scale engraved on the side of the instrument.
This instrument is ideal for quality control in painting and coating processes, and can be used on uniformly flat or curved surfaces, both concave and convex.
It is suitable for a wide range of liquid coatings, including industrial and decorative paints, automotive, anti-corrosion protective coatings, lacquering and varnishing of wood and metals.
Its design allows direct reading of wet film thickness and, from the solids content, estimation of the final dry thickness.
Made from stainless steel, portable, robust and reusable instrument with a long service life, suitable for both laboratory and in-field process control.

What coating thicknesses can be measured with a coating thickness gauge?
Thickness gauges are commonly used to check wet film thicknesses ranging from 10 μm to over 2,000 μm, covering everything from decorative paints to high-build anti-corrosion coatings.
What is the difference between a film gauge and a wet film comb?
Both instruments measure wet film thickness, but the wet film gauge typically offers higher resolution and better repeatability in applications where thicknesses between 0 and 500 μm are monitored with more stringent quality requirements.
How do you choose the appropriate range for a wet film gauge?
The range must be suited to the target coating thickness. For example, conventional industrial paints are typically applied at thicknesses between 50 and 200 μm, whilst some anti-corrosion systems or heavy-duty protective coatings can exceed 1,000 μm.
