Coating thickness gauge - for what purposes are they used?

Coatings are materials used as exterior spreads on construction elements to increase the life of a structure. One typical example is paint, which is sometimes mixed in with other inert materials to coat steel in structures to prevent early damage. These coatings are weather resistant. In cases where adverse conditions prevail, such as sea water or toxic environment, special additives are mixed into coating materials to help structures withstand the harshness. Of huge importance is the thickness of these coatings. One can’t just paint it over once on the surface and forget about it – the thickness determines how well the surface will fare. In this article, learn about coating thickness gauge – for what purposes they are used.

Basic information on coating thickness gauges

These gauges are used to measure the thickness of the coating on a surface. Thickness of coating impacts longevity of the structure, which is why it is important to be monitored. The principle used by these gauges is a simple one. It makes use of ultrasonic waves to measure thickness of material or coating on a material. It is a non-destructive method, which is why it is widely used. There are many variants of such gauges available to measure thickness of different materials – glass, ceramics, concrete and steel.

Purpose of coating thickness gauges

There is more than one purpose that these gauges serve in the construction industry. Below is a concise list of uses that coating thickness gauges have.

• For measuring thickness – this is evidently the major purpose of that these gauges serve. Measurement of coating thickness helps to estimate the life of a structural element, thus giving a better idea of the safety of the construction.

• For compliance – the construction industry has various compliances which need to be adhered to. Coating thickness also has certain minimum requirements for compliance purposes, which can be measured accurately by coating thickness gauges.

• For quality check – coating thickness gauges reveal anomalies in coating, making it possible to maintain a tighter check on quality. They can reveal recoats or repair work while coating, and this can help detect the weak links in construction early on.

Coating thickness gauges are now available online at very good prices.
