What is Coating Thickness Gauges?

Coating thickness gauges is PCE instruments that can determine the thickness of different layers of corrosion and variable layers. The coating thickness gauges can be used on all surfaces of metallic materials (metal, iron, nonferrous metal alloys). The coating thickness gauge uses magnetic induction or by means of analyzing an eddy current as measuring principles. It is very useful for most surfaces as the devices work non-destructive. Hence, materials have to be used afterwards. Therefore, these devices cannot miss a place where galvanizing processes are carried out. This work is perfectly suitable for quality control and other different production purposes in the process of anodizing, or galvanizing.

This thickness gauge can also determine the degree of hardness by means of plastic, glass and metal walls and windows. Usually, this equipment can be used with a head unit to test temperatures up to 300 C. You are also able to check the thickness of the wall for steam pipes and also other pressure pipes. Before starting measuring, you need to add gel on the sensor and the object that you want to be measured. Then, adjust the sound speed and the unit will display the thickness of the measured object. Each device has a different memory capacity to store a minimum of 10 measured values. Coating thickness gauge is usually designed for easy handling.

These devices are essential to measure the coatings in the automotive sector but also and also many more, for example:

– F Model: to measure lacquers, paints, plasters, etc. on iron and steel
–  N model: to measure lacquers, paints, plasters, etc. on non-ferrous metals (e.g. aluminum)
– FN model: (coating thickness gauges combined for ferrous and nonferrous substrates)
–    PT -200 Model : for layers / painting, and any other non-metallic coating bases

Each brand of coating thickness gauges will offer you with different specification. So figure out which one that will suit you best.
