Mechanical Magnetic Thickness Gauge

Mechanical magnetic thickness gauges measure coating thickness by detecting changes in magnetic attraction between a magnet and ferrous substrates. When the probe contacts the sample, the spring tension balances the magnetic attraction, causing the pointer to display the thickness value. This method is used to measure the thickness of non-magnetic coatings, such as paint or electroplating, on ferrous metal substrates.
Selection
Choose a flat or curved probe based on the shape of the substrate; match the measurement range to the coating thickness, typically selecting 0-2000 micrometers; consider accuracy requirements, with a standard error of ±3%; handheld devices are suitable for on-site use, while benchtop models are better for laboratories; check the rust resistance of the spring leaf and the stability of the pointer's zero return.
