Uniform Pressure Thickness Meter

The constant pressure thickness gauge measures the distance difference between the substrate and coating by contacting the material surface with a constant pressure probe, utilizing magnetic induction or eddy current principles. It is used to detect the thickness of coatings and electroplating layers to ensure coating uniformity. It is suitable for quality inspection of substrates such as metals and plastics.
Selection
When selecting, it is essential to match the material type with the measurement principle. Magnetic induction is typically used for metal substrates, while eddy current is preferred for non-metallic materials. Consider the measurement range to cover the thickness of the sample, and ensure the probe size is suitable for the shape of the measurement area. Verify the instrument's calibration certificate and its adaptability to environmental temperatures.
