Coating Measurement Instrument

Coating thickness gauges utilize magnetic induction or eddy current principles to non-destructively measure the thickness of coatings on substrate surfaces. They are used to monitor coating quality, ensuring uniformity and compliance with anti-corrosion performance standards in industries such as automotive, marine, and construction materials.
Selection
When selecting, consider the substrate type (metal/non-metal) and match the probe principle; choose the measurement range based on the coating thickness range; pay attention to the compatibility of the probe size with the workpiece shape; determine whether to use a portable or benchtop model based on the on-site environment; and ensure that the calibration certificate and measurement accuracy comply with industry standards.
