Coating Thickness Gauge for Non-magnetic Substrates

The non-magnetic substrate coating thickness gauge operates based on the eddy current principle. A probe generates a high-frequency electromagnetic field, inducing eddy currents in the non-magnetic metal substrate. The coating thickness is calculated by measuring changes in the eddy currents. It is used to detect coatings such as paint and plastic films on substrates like aluminum and copper, ensuring coating uniformity.
Selection
When selecting a non-magnetic substrate coating thickness gauge, consider the type of substrate material and coating range. The probe size should match the area being measured. Environmental factors such as temperature can affect accuracy. Ease of operation facilitates daily use, and calibration standards ensure measurement reliability.
