The Elcometer 154 Wet Film Combs are made from ABS plastic and are designed to be used once, and kept as a record of wet film thickness measurement for quality assurance or customer requirements. Metric and Imperial values are on the same comb, 50 to 800µm on one side, 2 to 32mils on the other.

Supplied in a pack containing 25 combs. Each comb has 16 measurement steps.

Using a wet film comb

Place a comb perpendicular to and touching the substrate. Hold the comb in position and wait a few seconds until the teeth are wet. Remove the comb from the film.  The wet film thickness lies between the biggest value ‘coated’ or ‘wet’ tooth and the smallest value ‘uncoated’ or ‘dry’ tooth.

The Elcometer 154 Wet Film Combs can be used in accordance with:

• ISO 2808-1A
• ISO 2808-7B*
• BS 3900-C5-7B*
• JIS K 5600-1-7
• NF T30-125

Elcometer 154 Wet Film Combs Instruction Manual

1. Hold the comb perpendicular to the wet film and press the edge of the comb into
2. the film until it is stable on the substrate.
3. Remove the comb from the wet film
4. Examine the teeth of the comb and locate the last tooth which is wetted.
5. Read the thickness value of this tooth. The wet film thickness is between this value and the thickness value of the next dry tooth.

In the example shown, the wet film thickness lies between 2400µm and 2600µm
To use the comb on pipes, ensure it is placed parallel to the longitudinal axis of the pipe

This is how to measure wet film thickness using a wet film thickness gauge, also known as a wet film comb.

Wet film combs measure wet film thickness, and are available in a variety of materials including stainless steel, aluminium and plastic, with various measurement scales ranging from 20µm to 3000µm.
