What Do You Mean by A Coating Thickness Gauge?

We make use of a coating thickness gauge for measuring dry film thickness which happens to be the most significant measurement at present in the coatings industry. It is possible to use dry film thickness measurements for assessing the expected life of a coating, the performance and appearance of the product, and also making sure that it complies with International Standards out there.

How Is It Possible to Measure Dry Film Thickness?

It is possible to measure dry film thickness by making use of 2 processes. The first one happens to be non-destructive coating thickness measurement that uses techniques that will not create any damage to the substrate or coating whatsoever. The second method is the destructive thickness measurement, in which case a cutter will be used for cutting the coating to the substrate.

It is possible to take the non-destructive coating thickness measurements on non-magnetic metal surfaces like aluminum or steel or on magnetic steel surfaces. Here, we like to mention that digital coating thickness gauges will be appropriate for measuring coating thickness on substrates that are metallic. We make use of electromagnetic induction for non-magnetic coatings on steel and other ferrous substrates while we use the eddy current principle for measuring non-conductive coatings on substrates that happen to be non-ferrous in nature.

Coating Thickness Gauges

In this article, we will mention the Elcometer coating thickness gauge which provides various types of gauges for measuring dry film thickness. The Elcometer coating thickness gauge consists of the Elcometer 121/4 Paint Inspection Gauge which happens to be a well-known way of figuring out dry film thickness on substrates that are non-metallic in nature.

The non-destructive coating thickness gauges from Elcometer consist of digital as well as mechanical coating thickness gauges that are appropriate for dry film testing coming with a comprehensive range of calibration foils and probes.

Mechanical Elcometer Coating Thickness Gauge

These types of gauges are known to offer affordable dry film thickness measurement and are ideal for working in high-risk zones, including underwater or high flammable atmospheres where there is a high risk of explosion and which can be caused by the usage of any electrical instrument.

Types Of Elcometer Coating Thickness Gauge

1. Elcometer 211 mechanical coating thickness gauge: Also referred to as the “Banana Gauge”, this particular model is being used in environments where it is difficult to use electronic instruments, for example, for inspection of underwater dry film coating thickness and highly flammable atmospheres in the production of oil and gas. This particular device is quite compact in size, as well as portable having a +/- 5% accuracy.

2. Digital Elcometer coating thickness gauge: The digital coating thickness gauges of this company are known to offer extremely reliable and accurate coating thickness measurements on ferrous as well as non-ferrous substrates.

Below, we have provided an example of this type of Elcometer coating thickness gauge.

3. Elcometer 415 industrial paint & powder thickness gauge: This particular model is known to offer simple, accurate, as well as fast measurements of coating thickness on thin, as well as smooth industrial paint and powder coatings. This digital coating thickness Gorge from Elcometer has the ability to switch between non-ferrous and ferrous metals and will be able to measure powder, as well as cured paint coatings up to 1000µm. This model will enable you to inspect a larger number of industrial materials within a short span of time with an astounding 60+ readings per minute reading rate.


There are also other types of Elcometer coating thickness gauges available on the market at present which we haven’t mentioned in this blog. Make sure to choose one according to your requirements and specifications.
