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

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

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.

www.elcometer.com en-4

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.

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.

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.
