Non-contact Coating Thickness Gauge

Non-contact coating thickness gauges calculate thickness by measuring the time difference or phase difference of reflected signals from the interface between the coating and the substrate using lasers or ultrasonic waves. They are used for detecting wet film and cured coating thickness, avoiding contact damage, and are suitable for on-site rapid measurement of soft materials such as paints and plastic films.
Selection
When selecting, consider the measurement range to cover the sample thickness, ensure accuracy meets process requirements, check compatibility between the substrate material and the instrument, assess environmental interference resistance, evaluate ease of operation, and verify data output functionality. For soft coatings, optical principles are preferred, while eddy current types are suitable for metal substrates.
