Portable Digital Coating Thickness Gauge TM260 adopts two thickness-measuring methods: magnetic induction (ferrous) and eddy current (non-ferrous). It can rapidly, nondestructively, and precisely measure the thickness of non-magnetic coating on magnetic metal substrate, and the thickness of non-conductive coating on non-magnetic metal substrate. This paint meter can be equipped with 6 optional probes for different applications. It is suitable for both field testing and laboratory research.
