Coating Thickness Meter

Know All About Coating Thickness Meters

It is a tool used to measure the thickness of coatings or paint applied to a surface. It is widely used in automotive, aerospace, and construction industries to ensure the quality and durability of coatings. It is also known as a coat thickness gauge or DFT meter, and is an essential tool for measuring the thickness of coatings on various surfaces. 

The coating thickness tester or paint DFT meter is available at different price points, with various models and brands, such as Elcometer paint thickness gauge and powder coating thickness gauge, offering different features.

How does Coating Thickness Meter work?

The instrument operates on the principle of magnetic induction or eddy current, depending on the type of coating and substrate being measured.

Here's how it works:

a) For ferrous substrates, a magnetic type paint thickness gauge is used. The instrument generates a magnetic field that induces a voltage in the coating, which is then measured to ensure the thickness of the coating.

b) For non-ferrous substrates, an eddy current type coating meter is used. The instrument generates an alternating magnetic field that induces eddy currents in the coating, which are then measured to determine the thickness of the coating.

In addition to knowing how to use them properly, it is also important that you use Data Loggers to store important data for further usage. 

Where is the Coating Thickness Meter commonly used?

Coating thickness gauges or DFT meters are used across various industries to measure the thickness of coatings on different substrates. The instrument is widely used in industries where coating thickness is critical for ensuring quality control and compliance with regulations.
