WET FILM COMBS
Elcometer 112, 3236
& 112AL
Precision formed, long lasting and reusable hexagonal stainless steel
wet lm combs. Available in a range of thicknesses measuring up to
3000μm (120mils) with 24 or 36 measurement steps depending on
the comb.
An aluminium version of the Elcometer 112 is also available, the
a
Elcometer 112AL . Supplied in packs of 10, each aluminium comb
has Metric (25 - 3000μm) on one side and Imperial (1 - 118mils) on
the other.
Elcometer 154
Made from ABS plastic designed to be used once and kept as a
record of wet lm thickness measurement for quality assurance or
customer requirements. Supplied in packs of 500, each comb has
Metric (50 - 800μm) on one side and Imperial (7 - 32mils) on the
other.
Elcometer 115
Precision formed, long lasting and reusable stainless steel wet lm
combs. Four separate wet lm thickness ranges are available up to a
maximum of 1250µm (50mils) and each comb has 10 measurement
steps (teeth).
Elcometer 3238
Similar to the Elcometer 115, the Elcometer 3238 provides the user
with more measurement steps (teeth) - 24 per comb. Three separate
wet lm thickness ranges are available up to a maximum of 1200µm
(48mils).
WET FILM WHEELS
Elcometer 3230
The Elcometer 3230 wet lm 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. By rolling the gauge
through a wet coating, the centre wheel eventually touches the lm.
This point on the scale indicates the thickness. Various wet lm
thickness ranges are available up to a maximum of 1000µm (40mils).
Elcometer 3230
(Coil Coating)
Similar to the Elcometer 3230 but the outer wheels are knurled to
allow measurements to be taken on slippery coatings or on fast
moving substrates. Two separate wet lm thickness ranges are
available; 0 - 50μm (0 - 2mils) and 0 - 100μm (0 - 4mils).

1 OVERVIEW
R
a The Elcometer 112AL can be customised with your logo. Please contact Elcometer or your local
Elcometer supplier for further information.

Before you start, ensure the wet film comb or wheel is clean, see
Section 3.3 ‘Cleaning After Test’ on page en-4, and undamaged as
damage to the wet film teeth or wheel circumference will affect the
readings.
3.1 USING A WET FILM COMB
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 2400μm and
2600μm.
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.

R
3.2 USING A WET FILM WHEEL
The procedure outlined below is for guidance only. Consult the
relevant Standard for full details of the applicable test procedure.
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.
d
3.3 CLEANING AFTER TEST
Clean the wet film comb or wheel after each test using a suitable
solvent. After cleaning, ensure that all materials are removed and that
the gauge is dry.
DO NOT use very aggressive solvents or wire brushes, metal
scrapers, metal files, or other metallic tools for cleaning.
b
Store the wet film comb or wheel in the wallet / case provided when
not in use.
b A storage wallet / case is not supplied with the Elcometer 112AL and Elcometer 154.
d Does not apply to the Elcometer 154 which are designed to be used once and kept as a record of wet lm
thickness measurement for quality assurance or customer requirements.
