Non-ferrous dry film Tester

Non-ferrous dry film thickness gauges are used to measure the coating thickness on the surface of non-ferromagnetic substrates. The principle is based on the eddy current effect, where the probe generates a high-frequency electromagnetic field to induce eddy currents in the conductive substrate, and the coating thickness is calculated by detecting changes in the eddy currents. Its purpose is quality control, and it is applied in coating inspection on substrates such as aluminum, copper, and plastics.
Selection
When selecting a non-ferrous dry film thickness gauge, considerations include the substrate type and coating range, as well as matching the probe size and shape to the measurement surface. Attention should be paid to the instrument's calibration method and accuracy, ensuring ease of operation and data storage capabilities. Environmental adaptability, such as temperature stability, must meet the usage conditions.
