It is important that a coating is applied to the correct thickness. Applying too much wet coating will not only waste time and money, but there is also a possibility of the coating cracking during the curing process. Too little coating and there is a chance that the substrate will not be sufficiently covered.
To control process variables, it is often desirable to measure whilst the film is still wet. Wet film measurements are also useful for systems where the dry film thickness can only be measured destructively.

The Elcometer 112 & 3236 Hexagonal Stainless Steel Wet Film Combs are Precision formed in stainless steel to be long-lasting and reusable, these hexagonal 6 sided Wet Film Combs are supplied in a range of thicknesses and can measure up to a maximum thickness of 3000µm. This high upper value allows measurement of thick coatings which are difficult to test by other methods. Range : 25 to 3000 mic. Conforms to ISO, ASTM, BS, NFT

The Elcometer 112 Hexagonal Aluminium Wet Film Combs are precision formed aluminium hexagonal comb, with 6 sides providing a wide scale range. It is durable and can be cleaned and reused but not as durable as the engraved Stainless Steel Wet Film Comb. Range : 25 to 3000 mic. Conforms to ISO, ASTM, BS, NFT

The Elcometer 115 Stainless Steel Wet Film Combs are etched film combs allowing you to measure whether you are over or undercoating before the coating has dried. They are made from stainless steel to be long-lasting and reusable and are supplied in Metric and Imperial values on the same comb. Four separate ranges of thicknesses are available from 25 mic up to a maximum thickness of 1270µm (50mils). Each comb has 10 measurements (or teeth) per comb. Range : 25 to 1270 mic. Conforms to ISO, ASTM, BS, NFT

Similar to the Elcometer 115, the Elcometer 3238 Long Edge Wet Film Combs provides the user with more measurement points (teeth). These rectangular wet film combs are available in 3 ranges up to a maximum thickness of 1200µm– supplied either separately or in a set of 3. Range : 25 to 1200 mic. Conforms to ISO, ASTM, BS, NFT |

Made from ABS plastic, the Elcometer 154 Wet Film Combs are designed to be used only once and kept as a record of wet film thickness measurement for your ISO or customer requirements. Both Metric and Imperial values are on the same comb, 50 to 800µm on one side, 2 to 32mils on the reverse. Range : 50 to 800 mic. Conforms to ISO, ASTM, BS, NFT

Formally known as the Elcometer 120, the Elcometer 3230 Wet Film Wheel consists of three circles. The central circle is of smaller diameter and is eccentric of the two outer circles. By rolling the gauge through a wet coating, the centre disc eventually touches the film. This point on the scale indicates the thickness. Various measurement ranges from 0 to 25µm - 0 to 3000µm are available. Conforms to ISO, ASTM, BS, NFT

The Elcometer 3230-1 Coil Coating Wet Film Wheels is similar to the Elcometer 3230 Wet Film Wheels, but designed for use in the coil coating process. These coil coating wheels consist of three circles. The outer circles are knurled to allow measurements to be taken on slippery coatings or on fast moving substrates. Range : 25 to 300 mic. Conforms to ISO, ASTM, BS, NF

The Elcometer 3233 Pfund Thickness Gauge is an instrument that consists of two concentric cylinders, one sliding inside the other. A spherical glass lens is fitted to the end of the central cylinder and when pressed into the wet film it leaves a trace. The diameter of this mark depends on the thickness of the coating. Range : 2.25 to 360 mic. Conforms to ASTM, NF
