Mechanical Film Thickness Gauge

The mechanical coating thickness gauge measures the thickness by contacting the probe to the coating surface and the substrate, then calculating the height difference between them. It is used for rapid on-site inspections in industries such as coatings and plastics, offering simple operation but requiring a flat surface.
Selection
When selecting, consider the matching of probe type to the hardness and softness of the coating. Choose a flat or curved model based on the shape of the substrate. The measuring range should cover the expected thickness. Environmental conditions determine whether a standard or explosion-proof design is needed, and the calibration method should be selected according to accuracy requirements.
