Linshang LS223 coating thickness gauge also called coating thickness tester is an instrument that separates the host from the probe. The measuring range is 5000¼m 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.
