Point-contact coating thickness Gauge

The point-contact coating thickness gauge measures the physical property differences at the interface between the substrate and the coating by using a probe to contact the coating surface, employing the principles of magnetic induction or eddy current, and directly converts these differences into thickness values. It is commonly used for rapid on-site detection of the thickness of coatings such as paint or plating on metal substrates, with frequent applications in automotive repair and anti-corrosion for steel structures.
Selection
Select magnetic induction (ferrous) or eddy current (non-ferrous) models based on the substrate type; the measurement range should cover the expected coating thickness; consider probe size to accommodate flat or curved surfaces; portable designs are suitable for on-site use, while fixed types are ideal for laboratories; ensure environmental temperature adaptability and calibration certificates meet routine testing requirements.
