LS223 coating thickness gauge also called coating thickness tester is an instrument that separates the host from the probe. The measuring range is 5000μm and the meter can automatically identify the measuring substrate. This instrument uses both Hall Effect and eddy current measurement principles to measure the non-magnetic coating thickness on magnetic substrates and the non-conductive coating thickness on non-magnetic substrates. It is a dual-use instrument for both ferrous and non-ferrous substrates. LS223 coating thickness tester is widely used in hardware manufacturing, shipbuilding, aerospace, mechanical equipment evaluation and other fields. This meter is especially suitable for large thickness coating inspection.
