When users choose a coating Thickness Gauge, in addition to choosing different measurement principles, measurement ranges and accuracy based on different substrates and coating thicknesses, they also need to consider the environment of the measured object. Especially for non-planar objects, such as pipes, water cups, etc., most Thickness Gauges will mark this data.
The minimum convex radius and convex radius of the curved surface in the specification parameters are to ensure accurate measurement on the curved surface. The surface radius requirements of the coating Thickness Gauge are generally related to the probe structure and the coating Thickness Gauge itself. The measurement of the inner wall paint film is generally selected. "Strip line" coating Thickness Gauge, both can be used for outer wall paint film.


The following table is the model and curvature table of the EPK McCourt coating Thickness Gauge. EPK is a common mechanical Thickness Gauge that can measure curved surfaces. When measuring cylindrical or circular edges, you can use the V-shaped on the measuring nozzle of the instrument. mouth. When measuring a concave surface, it is the same as measuring a plane, but pay attention to the limitation of the minimum curvature.
