Elcometer. For more information visit our website at www.elcometer.com
1 ABOUT THIS GAUGE
This gauge is a simple but effective instrument used to determine the thickness of wet paints and similar
coatings immediately after application. The expected dry film thickness can then be calculated.
1.1 WET FILM COMBS
The edge of the comb is placed into the wet film and then removed. The thickness of the wet film is
determined by examining the paint left on the teeth of the comb and the thickness scale marked on the front
face of the comb.
Elcometer 112 & Elcometer 3236
Precision formed in stainless steel to be long-lasting and reusable, these hexagonal wet film combs are
supplied in a range of thicknesses up to a maximum of 3000 µm (120 mils). This high upper value allows
measurement of thick coatings which are difficult totest byother methods. An aluminiumversion is available
(Elcometer 112AL); this model is not as accurate as the high precision versions but it does provide a low
cost alternative for measurement of wet film thickness.

Elcometer 115
These precision film combs, formed in stainless steel to be long-lasting and reusable, are supplied in Metric
or Imperial values. Four separate ranges of thicknesses are available up to a maximum thickness of
1250 µm (50 mils). Each comb has 10 measurements (or teeth) per comb.
Elcometer 154
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 800 µm on one side, 2 to 32 mils on the other.
Elcometer 3238
Similar to the Elcometer 115, the Elcometer 3238 provides the user with more measurement points (teeth).
These rectangular wet film combs are available in 3 ranges up to amaximumthickness of 1200 µm (50 mils)
- supplied either separately or in a set of 3.
1.2 WET FILM WHEEL
Elcometer 3230
Formerly known as the Elcometer 120, the Elcometer 3230 wet film wheel consists of a central eccentric
wheel and two outer concentric wheels. The diameter of the outer wheels is greater than that of the central
wheel. The gauge is rolled across the wet paint film and at some point the central wheel will touch the paint.
A scale on the outside of the wheel indicates the paint film thickness at this point. Various measurement
ranges from 0 to 25 µm to 0 to 1000 µm (0 to 1 mil - 0 to 40 mils) are available.
Coil Coating Wet Film Wheel; similar to the Elcometer 3230 wet film wheels, but the outer wheels are
knurled to allow measurements to be taken on slippery coatings or on fast moving substrates.

2 USING A WET FILM COMB
Before you start, ensure your Elcometer Wet Film Comb is clean
and undamaged.
1. Hold the comb perpendicular to the wet film and press the
edge of the comb into the film until it is stable on the
substrate.
2. Remove the comb from the wet film.
3. Examine the teeth of the comb and locate the last tooth
which is wetted. 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
2400 µm and 2600 µm.
To use the comb on pipes, ensure it is placed parallel to the
longitudinal axis of the pipe.
On rough surfaces, measurements will be made from the
surface peaks and therefore will represent the minimum
wet film thickness.

3 USING A WET FILM WHEEL
Take care to avoid damaging your Elcometer Wet Film Wheel. Damage to the circumference of the
wheel will affect the readings and the gauge will have to be replaced.
Before you start, ensure your Elcometer Wet Film Wheel is clean and undamaged. Read and understand
the test procedure described in the applicable test standard.
The procedure depends upon which standard you are testing to. Consult your test standard for further
details.
1. Using a finger and thumb, hold the wheel by its central
spindle with the maximum reading on the scale nearest to
the paint film.
2. Place the wheel into the wet film ensuring that the wheel
is perpendicular to the film.
3. Roll the wheel across the film through 360°/180°
(depending upon standard) and then remove from the
surface.
4. Locate the first point on the central wheel where the paint
has adhered. Read the wet film thickness from the scale
on the side of the wheel at this point.
Repeat the procedure at least twice in different places to obtain representative results.
To use the wheel on pipes, roll the wheel at right angles to the longitudinal axis of the pipe.
On rough surfaces, measurements will be made from the surface peaks and therefore will represent the
minimum wet film thickness.

4 CLEANING AFTER A TEST
Clean your gauge after a test (except Elcometer 154 Plastic Wet Film Comb).
Do not use very aggressive solvents or wire brushes, metal scrapers, metal files or other metallic tools
for cleaning.
Clean the gauge using a suitable solvent only.
After cleaning, ensure that all materials are removed and that the gauge is dry.
Use the case provided to store the gauge when it is not being used.
5 MAINTENANCE
Elcometer products are designed to give many years reliable service under normal operating and storage
conditions.
Regular calibration checks over the life of the gauge are a requirement of quality management procedures
e.g. ISO 9000 and other standards. For checks and certification contact Elcometer or your local supplier.
