Coating Thickness Meter for Non-metallic Substrates

Non-metallic substrate coating thickness gauges utilize electromagnetic induction or eddy current principles to measure thickness by detecting changes in the electromagnetic field between the probe and the coating. They are used to inspect surface coatings on non-metallic substrates such as plastics and wood, ensuring uniformity of the coating application.
Selection
When selecting, consider the substrate type and coating characteristics, match the instrument's measurement range and accuracy, ensure the probe size is suitable for the shape of the measured object, verify the validity of the calibration certificate, and assess the impact of the operating environment on measurements.
