Pointer-type Magnetic Thickness Gauge

The pointer-type magnetic thickness gauge operates based on the principle of magnetic attraction. The probe generates a magnetic field, and when measuring the thickness of a magnetic coating on a non-magnetic substrate, changes in magnetic resistance drive the pointer to display the value. It is used to detect the thickness of coatings such as paint or galvanized layers on steel surfaces, enabling rapid on-site measurements in fields like steel structure corrosion protection and automotive manufacturing.
Selection
When selecting, consider the shape of the substrate to match the probe type: use a flat probe for flat surfaces and a convex probe for curved surfaces. The measurement range should cover common coating thicknesses. Environmental temperature can affect pointer stability, so regular calibration with standard blocks is necessary. A portable design is suitable for outdoor use, and proper training ensures accurate readings.
