Two measurement principles of paint thickness meters

Common paint thickness meters generally include two measuring principles, magnetic and eddy current, and are divided into integrated and split types. The integrated type means that the probe and the main unit are together; the split type means that the probe and the main unit are separated. Linshang's LS220 is an integrated paint thickness meter and LS221 is a split coating thickness gauge.
Coating Thickness Gauge
Linshang Coating Thickness Gauge adopts Hall effect and eddy current effect and can be used to measure non-magnetic coatings such as paint, varnish, enamel, chrome, galvanized, etc. on ferromagnetic metal substrates such as steel; eddy current principle means that the instrument can be used for copper Measurement of coatings, anodic oxide coatings, ceramics and other non-conductive coatings on non-magnetic metal substrates such as aluminum, die-cast zinc, brass, etc.
Linshang's coating thickness gauge has both magnetic measurement principle and eddy current measurement principle. The magnetic measurement principle is used to detect the thickness of the coating on the iron substrate, and the eddy current principle is used to detect the thickness of the coating on the non-ferrous substrate. Therefore, Linshang’s coating thickness gauge has three measurement modes, namely, iron-based (Fe) measurement mode, non-ferrous-based (NFe) measurement mode, and automatic identification (Fe/NFe) mode. The measurement mode can be selected according to the actual situation.
