Plated Layer Thickness Meter

The coating thickness gauge utilizes magnetic induction, eddy current, or ultrasonic principles to perform non-destructive measurement of coating thickness on metal or non-metal substrates. It is used to inspect the quality of anti-corrosion layers and electroplated coatings, enabling rapid on-site monitoring of coating uniformity in industries such as automotive, shipbuilding, and pipelines.
Selection
When selecting, confirm that the substrate properties (magnetic/conductive) match the probe type, and ensure the measurement range covers the thickness of the coating to be tested. Consider the compatibility of the substrate shape with the probe structure and the impact of environmental temperature on accuracy. Verify the instrument's calibration certificate and error range. Portable devices are suitable for field operations.
