Paint Thickness Measurement Gauge

The paint thickness gauge utilizes the principles of magnetic induction or eddy current. When the probe contacts the coating, it generates changes in the magnetic field, which are converted into electrical signals to directly display the thickness value. It is used to measure the thickness of paint or powder coatings on metal substrates and monitor coating uniformity in industries such as automotive manufacturing and furniture finishing.
