Elcometer 112AL, 112 & 3236 Hexagonal Wet Film Combs

The Elcometer Hexagonal Wet Film Combs are designed for wet film thickness measurements and come in a range of thickness scales.

Elcometer 112AL Punched Wet Film Combs (Aluminium)

These punched aluminium combs offer the user a low cost method of measuring the wet film thickness.

The Elcometer 112AL, being punched from aluminium, is not as accurate as precision formed stainless steel wet film combs and has a shorter lifespan.

Supplied in a pack of 10 combs, each comb has Metric (25 - 3000μm) on one side and Imperial (1 - 118mils) on the other.

The Elcometer 112AL can be customised with your logo. Please contact Elcometer for further details.
 
Elcometer 112 & 3236 Hexagonal Wet Film Combs (Stainless Steel)

These hexagonal precision formed stainless steel wet film combs are long lasting, reusable and supplied in a range of thicknesses measuring up to 3000μm (120mils).

These six sided combs vary in size, giving either 24 or 36 measurement steps, depending upon the comb, thus providing increased accuracy.

Elcometer 115 Wet Film Combs

These reusable precision stainless steel wet film combs are made to be long lasting and are supplied with either Metric or Imperial film thickness measurements.

Four separate wet film thickness ranges are available up to a maximum of 1270µm / 50mils and are manufactured to an accuracy of 5% or 2.5µm (0.01mil), whichever is the greater.

Each wet film comb has 10 measurement steps (teeth).

Elcometer 3238 Long Edge Wet Film Combs

These stainless steel wet film combs are wire eroded to provide an accuracy of ±2.5µm (0.01mil) and are supplied with either Metric or Imperial wet film thickness measurements.

Each wet film comb has 24 measurement stages (teeth) providing a more accurate wet film thickness value.

Elcometer 154 Plastic Wet Film Combs

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 wet film comb, 50 to 800µm on one side, 2 to 32mils on the other.

Supplied in a pack containing 500 wet film combs. Each comb has 16 measurement steps.

Elcometer 3230 Wet Film Wheels

The Elcometer 3230 Wet Film Wheel is a high precision, accurate and easy to use instrument which consists of a set of three wheels.

The central wheel is of a smaller diameter and is eccentric relative to the two outer wheels.

By rolling the gauge through a wet coating, the centre wheel eventually touches the film. This point on the scale indicates the thickness.

A convenient mounting handle for the wheel is available in two lengths; 15cm (6”) & 50cm (19”); please order separately.

When the volume to solids ratio of the coating is known (generally found on the product data sheet supplied by the manufacturer), the wet film thickness can be used to predict the dry film thickness.

Several measurement ranges between 0 to 25µm and 0 to1000µm (0 to 1mil and 0 to 40mils) are available.

  • Continuous scale produces ±5% measurement accuracy
  • Suitable for flat and curved surfaces

Elcometer 3230 Coil Coating Wet Film Wheels

This instrument is similar to the Elcometer 3230 Wet Film Wheel, but is designed for use in the coil coating process.

The outer wheels are knurled to allow measurements to be taken on slippery coatings or on fast moving substrates.

By rolling the gauge through a wet coating, the centre wheel eventually touches the film. This point on the scale indicates the thickness.

When the volume to solids ratio of the coating is known (generally found on the product data sheet supplied by the manufacturer), the wet film thickness can be used to predict the dry film thickness.

Elcometer 3233 Pfund Thickness Gauge

The Elcometer 3233 Pfund Thickness Gauge is used to measure film thickness of wet translucent products such as varnishes, paints and oils.

Available in aluminium or stainless steel this instrument 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, leaves a circular trace.

The diameter of the mark on the lens is measured and, using the supplied conversion table, the thickness of the coating can be easily assessed.

  • Ideal for measuring the thickness of wet translucent products such as varnishes, oils etc.
  • Measurement range of 2.25 - 360μm (0.09 - 14.17mils)

Elcometer 550 Non-Contact Powder Thickness Gauge

Using third generation proven airborne ultrasonic technology, the new Elcometer 550 Powder Thickness Gauge accurately predicts cured coating thickness by non-contact measurement of coating powders.

  • Accurately predicts the cured coating thickness within ± 5% of the reading or ±5µm (±0.25mils)
  • Ergonomic gun designed for comfort when taking multiple readings
  • Hand-held probe allows easy positioning of the sensor for fast measurement
  • Large illuminated colour display with positioning graph to guide orientation of sensor probe
  • Tough aluminium case, ideal for testing in an industrial environment

By carefully controlling the thickness of powder applied to a product, you can minimise your powder usage and ensure the quality of your coating. As contact measurement solutions damage the finish and do not predict the cured coating thickness, measuring the powder thickness pre-cure requires a non-contact solution.

Easy to Use

  • Easy to read, large colour display
  • Adjustable screen brightness for all test conditions
  • Ergonomic probe - ideal for continuous testing
  • Can be used straight out of the box with minimal set up time
  • On-screen guidance graph and handle LEDs help you orientate the probe sensor for fast, accurate measurements

Reliable

  • Fast, accurate and repeatable results
  • Can be used in accordance with ASTM D7378-Procedure C
  • Proven, third generation, airborne ultrasonic technology
  • User-programmable set up to account for varying powder shrinkage rates

Enhanced Technology

  • Measure thicknesses from 30 - 110μm (1.18 - 4.4mils)
  • 1mm² (0.04 sq in) measurement area - ideal for flat, curved and small surfaces
  • Test coatings on a wide range of substrates, including metal, wood, MDF, plastic and pre-coated surfaces
  • Laser targeting to accurately position the gauge at the correct distance from the surface to be measured

Elcometer 155 Uncured Powder Film Comb

Available in four scale ranges, the Elcometer 155 Uncured Powder Film Comb is designed to measure uncured powder coating film thickness.

This enables the application system to be set up and fine tuned prior to the curing process. In turn, this will reduce the amount of scrap and over-spray.

Place the comb into the powder and slide the comb along the surface. The measurement points (or teeth) are pointed and allow the powder to flow around them.
The thickness of the powder lies between the highest value where a drag mark is visible and the lowest value where a drag mark has not been produced.

Note: The thickness of a coating prior to cure is not the same value after curing but there is a correlation. The powder comb is suitable as a guide only.

The Elcometer 155 is not available for sale in the USA.
