Micron Thickness Meter

The micrometer thickness gauge measures the distance difference between the material surface and the probe through contact or non-contact methods, and calculates the thickness of coatings or thin films using principles such as electromagnetic induction, ultrasonic waves, or optical reflection. It is used to detect the uniformity of paints, coatings, plastic films, etc., and to monitor thickness deviations in real-time on production lines.
Selection
When selecting, consider the measurement range to cover the sample thickness. Contact methods are suitable for hard materials, while non-contact methods are used for soft or high-temperature surfaces. Match the probe type to the substrate material—use eddy current principles for metal substrates and ultrasonic methods for non-metallic materials. Pay attention to environmental adaptability, including temperature and vibration effects, and ensure the calibration method aligns with routine inspection frequency.
