A coating thickness gauge is also referred to as a paint meter. Why? It is because this instrument is useful in measuring the thickness of a dry film.

Experts say that dry film thickness is perhaps the critical measurement in the coatings industry. This is because the impact of thickness is big on the quality and cost of the coating process.

Dry film thickness measurements are also very important in evaluating the expected life of the coating. Thus, it becomes easy to calculate the commercial viability of the task.

It also plays an important role in the appearance and performance of the product. It ensures compliance with all International Standards.

MEXTECH is a well-known name in the niche and one of the leading Thickness Meter Manufacturers in Tamilnadu.

How does it measure Dry Film Thickness?

Dry film thickness (DFT) can be measured by using two methods:

• Destructive thickness measurement: In this method, the coating is cut to the substrate with the help of a cutter
• Non-destructive thickness measurement: This method does not cause any damage to the coating or the substrate. Examples are magnetic, magnetic induction, and eddy current thickness measurement methods.

In the non-destructive coating thickness measurement, it is possible to take measurements on either magnetic steel surfaces or non-magnetic metal surfaces.

Digital coating thickness gauges are ideal for measuring coating thickness on metallic substrates.

In the measurement of the thickness of non-magnetic coatings on ferrous substrates such as steel, we can use electromagnetic induction.

Whereas, for non-conductive coatings on non-ferrous metal substrates we can use the eddy current principle.

Coating Thickness Gauges

Coating thickness gauge suppliers offer a wide range of measurement equipment to cater to the needs of measuring dry film thickness. They provide accurate and perfect readings.

The range of destructive coating thickness gauges includes the Paint Inspection Gauge or PIG. This method is quite popular for determining dry film thicknesses on non-metallic substrates.

The range of non-destructive coating thickness gauges includes several digital as well as mechanical coating thickness gauges.

They are suitable for dry film testing, and various types of probes and calibration foils to meet the needs of different applications.

Mechanical Gauges

You can find a range of mechanical coating thickness gauges also. They offer a more cost-effective dry film thickness measurement method. Mechanical gauges are suitable in high-risk applications where you have high temperatures or flammable material. They are also useful in special conditions like underwater or where the risk of explosion due to electronic circuits is high.

The simplest coating thickness gauge gives fast and immediate results. There are very precise, complex and accurate thickness gauges that are ideal in cold weather and underwater applications.

Digital gauges

The digital coating thickness gauges are specifically designed for highly accurate, reliable, and repeatable thickness measurements.

They can work on all substrates, ferrous or non-ferrous. You can find these gauges with integral or separate probes. Industrial paint & powder thickness gauges are also widely used and they are important instruments in different applications.
