Metravi CTG-10

The Metravi CTG-10 Coating Thickness Gauge is a high-performance instrument that can measure coating thickness on both ferrous and non-ferrous metals.

A high precision device for conductive coating measurement, stable and reliable performance and non-destructive measurement, etc. It is a necessary instrument for automobile manufacturing, sales, evaluation, metal processing, painting, inspection and other industries. It is widely used in manufacturing, metal processing, marine mechanics, bullet trains, quality supervision, and other fields.

The Metravi CTG-10 Coating Thickness Gauge is based on the principles of electromagnetic induction and eddy current measurement.
The principle of electromagnetic induction measurement is to measure the coating thickness according to the size of the magnetic flux flowing from the sensor through the non-ferrous magnetic coating into the ferromagnetic substrate. The symbol is Fe. It can measure non-conductive or conductive coatings on magnetically permeable metals such as iron and steel (for example: galvanised steel sheet).
The principle of eddy current measurement is to measure the coating thickness according to the difference in the eddy current formed by an AC magnetic field on a non-magnetic metal substrate (such as aluminium). The symbol is NFe.

The Metravi CTG-10 Coating Thickness Gauge can also measure non-conductive coatings on non-magnetic metal materials such as aluminium and copper, as in the substrate is metal, and the coating cannot conduct electricity.
