What is a coating thickness gauge?

Coating thickness gauges (also referred to as a paint meter) are used to measure dry film thickness. The Elcometer range of dry film thickness gauges (DFT gauge), provide reliable and accurate coating thickness measurements on almost any metal substrate, whether ferrous or non-ferrous.

How thick is a coating of paint?

In the U.S. the thickness of paint is expressed in mils (one mil equals 1/1000 of inch). The rest of the world expresses coating thickness in microns (1 micron = 1 millionth of a meter and 25.4 microns = . 001” inch or 1 mil).

How do thickness gauges work?

A rugged ultrasonic thickness gauge determines sample thickness by measuring the amount of time it takes for sound to traverse from the transducer through the material to the back end of a part and back. The ultrasonic thickness gauge then calculates the data based on the speed of the sound through the tested sample.

What is a good paint thickness reading?

A typical factory paint job will measure between 4.0 mils and 6.0 mils. The clear coat will generally measure between 1.5 and 2.2 mils thick. The alternative measurement is called a micron. A micron is a metric unit that equals one millionth of a meter, or 1/1000 of a millimeter.

What is BMW paint thickness?

Tech Note BMW: After all coats are applied, the total paint thickness is 120 microns or about the thickness of 5 human hairs.

How thick is a coat of paint in MM?

Coating Thickness Conversion Table

25.4 0.025 1
50.8 0.051 2
76.2 0.076 3
101.6 0.102 4

What is mil gauge?

What is a wet mil film gauge? A wet film gauge is a tool used to quickly and easily measure the thickness of your adhesive coating after it has been applied to your substrate. As indicated by the name, the tool measures thickness in units of mils. One mil is equal to a thousandth of an inch.

What is DFT thickness?

Dry film thickness (DFT) is the thickness of a coating as measured above the substrate. This can consist of a single layer or multiple layers. DFT is measured for cured coatings (after the coating dries). Film thickness is measured to ensure its compliance with ASTM, ISO and other specifications.

What is ereray paint coating thickness gauge?

ERAY Paint Coating Thickness Gauge The tool uses electromagnetic induction, it measures the depth cover on magnetic materials, such as aluminum, chrome, copper, lacquer, rubber, and paint on magnetic substrate (iron, alloy, metal, and magnetic stainless steel).

Is a coating thickness gauge good enough?

The layer depth gauge is useful in the diagnosis of practiced cars to distinguish factory painted cars from repaired ones. Still, they are also used in professional paint shops to determine the quality of the coating finally. However, a coating thickness gauge is not always good enough. They may have some limitations.

What kind of gauge do you use to measure non magnetic coatings?

Positector PP-1 magnetic pull-off thickness gage measures non-magnetic coatings such as paint, enamel, plating, & hot-dip galvanizing on steel. Coating Thickness Gauge with extended waterproof probes for under water measurement.

What is the best paint thickness gauge for intumescent fire resistive coatings?

DeFelsko offers many models of the PosiTector 6000 thickness gage that are ideal for measuring the total thickness of intumescent fire resistive coatings. DeFelsko manufactures various hand-held, non-destructive paint thickness gauges that are ideal for measuring coating thickness on wires.
