A DFT (Dry Film Thickness) Coating Thickness Gauge is a device used to measure the thickness of a coating on a substrate. It is commonly used in industries such as automotive, aerospace, marine, and construction to ensure that coatings are applied correctly and meet the required specifications.The gauge works by using a non-destructive method to measure the thickness of a coating without damaging it. It does this by using one of two methods: magnetic induction or eddy current. The magnetic induction method is used for non-magnetic coatings on magnetic substrates, while the eddy current method is used for non-conductive coatings on conductive substrates.
The DFT Coating Thickness Gauge consists of a handheld instrument with a probe that is placed on the surface of the coated substrate. The gauge sends a signal to the probe, which then measures the thickness of the coating and displays it on the instrument's screen.
