Marking line coating thickness Gauge

The marking line coating thickness gauge measures the thickness of coatings on substrate surfaces through magnetic induction or eddy current principles. The probe contacts the coating, generating changes in the electromagnetic field, and the instrument calculates the signal difference after the coating blocks it to obtain thickness data. It is used to detect the thickness of coatings such as paint or plastic on metal substrates, ensuring the quality of the coating application.
Selection
When selecting, consider the substrate type: use the magnetic induction principle for iron-based materials and the eddy current principle for non-iron-based materials. Choose the measurement range based on the coating thickness, typically 0-2000 micrometers. Check the accuracy error value: ±1 micrometer for laboratory use and ±3 micrometers for field use. Ensure the probe size is suitable for the curvature of the measurement surface, opting for a small probe for curved surfaces. Verify the instrument's calibration certificate and protection rating.
