Inbuilt Printer Dry Film Paint Thickness Tester Elcometer Coating Thickness Gauge TG110
The TG110 measures the thickness of non-magnetic materials (e.g. paint, plastic, porcelain enamel, copper, zinc, aluminium, chrome etc.) on magnetic materials (e.g. iron, nickle etc.) . often used to measure the thickness of galvanizing layer, lacquer layer, porcelain enamel layer, phosphide layer, copper tile, aluminium tile, some alloy tile, paper etc.
The gauge adopts two thickness-measuring methods: magnetic induction method and eddy current method.
Magnetic Induction method: The probe and the magnetic metal substrate will form a closed magnetic circuit when probe contacting with the coating; the magnetic resistance of closed magnetic circuit varies due to the existing of non-magnetic coating. The thickness of the coating can be measured through the variation of magnetic resistance.
Eddy current method: The high frequency alternating current generates an electromagnetic field in the probe coil; eddy current will be formed on metal substrate when the probe contacting with the coating, and the eddy current has an effect of feedback on the coil in probe. The thickness of the coating can be calculated through measuring the effect of feedback.
The range of applications is indicated by the probes available.
-F probes work on the magnetic induction principle and should be used for non-magnetic coatings such as aluminum, chrome, copper, zinc, paint and varnish, enamel, rubber etc., on an iron or steel substrate; they are also suitable for alloyed and hardened magnetic steel.
- N probes work on the eddy-current principle and should be used for insulating coatings on all non-ferrous metals and on austenitic stainless steels, e.g. paint, anodizing coatings, ceramics, etc. applied on aluminum, copper, zinc die-casting, brass, etc.
