LS220 coating Thickness Gauge is widely used in mechanical equipment evaluation, shipbuilding industry, automobile evaluation, hardware manufacturing, aerospace and other industries. In order to achieve the protection or decoration of various materials in the industry. Usually, methods such as spraying non-ferrous metal covering, phosphating, and anodizing treatment are used, so that concepts such as coating and plating appear. Often referred to as "cladding".
Linshang LS220 coating Thickness Gauge is dual-purpose for iron and aluminum, and can freely switch between three different measurement modes: Fe (iron-based measurement), NFe (non-ferrous-based measurement), AUTO (automatic identification mode).
Among them, the iron-based measurement of Fe is based on the principle of magnetic induction. When the probe is in close contact with the magnetic substrate with the coating, the probe and the magnetic substrate form a closed magnetic circuit. The thickness of the coating has a relationship with the magnetic resistance of the magnetic circuit. By detecting the magnetic resistance Change to achieve the purpose of measuring the thickness of this coating.
NFe non-ferrous base measurement uses the principle of eddy current effect. When the probe is in close contact with the non-magnetic substrate with coating, the probe will cause the substrate to generate eddy current, and the feedback effect of eddy current on the probe has a relationship with the coating thickness. By detecting this feedback To achieve the purpose of measuring the coating thickness.
The AUTO automatic mode combines these two principles, and automatically switches modes during measurement.
The coating Thickness Gauge LS220 has the characteristics of simple operation, stable zero position, long-term use, fast measurement, and can be used after zero adjustment. It is very suitable for on-site quality inspection of used cars.
