Paint Film Thickness Gauge

A paint film gauge measures coating thickness through magnetic induction or eddy current principles. The magnetic induction method is used for steel substrates, while the eddy current method is applied to non-ferrous metal substrates. It is used to detect the thickness of coatings such as paint and electroplating, ensuring that the coating quality meets standards.
Selection
Select instruments based on magnetic induction or eddy current principles according to the substrate type. Consider measurement range, accuracy, and probe size. Check the calibration certificate and protection rating. Test the influence of substrate curvature and surface roughness on measurements.
