Eddy-Current Dry Film Thickness Gauge

The instrument utilizes a probe to generate a high-frequency electromagnetic field, creating eddy currents on metal substrates. By measuring changes in the probe impedance caused by the eddy currents, it calculates the thickness of non-conductive coatings. It is suitable for detecting paint films and plastic layers on non-ferrous metal surfaces such as aluminum and copper, and is widely used in quality control in the automotive and household appliance industries.
Selection
Select the corresponding model based on the substrate type, ensuring the measurement range covers the thickness of the coating to be tested. Consider the compatibility of the probe size with the measurement area, and choose a small probe for curved surface measurements. Verify the instrument calibration method and the configuration of standard calibration pieces. Select environmental temperature adaptability and data storage functions according to actual needs.
