| Probes |
| Probe modules are available for both Electromagnetic Induction and Eddy Current measurements of coating thickness. Ferrous (F) Modules: Using the electromagnetic induction probe, a number of F modules are available for different coating thickness ranges and a variety of probe capabilities. These modules all measure nonmagnetic coatings such as paint, plastic, enamel, powder, rubber, ceramic, electroplating, hard chrome, galvanizing, zinc sprayed metals, etc., on magnetic substrates eg. steel, cast iron, ferritic stainless steel, etc. Nonferrous (N) Modules: Using the eddy current principle the N modules measure nonconductive coatings such as anodizing, paint powders, lacquers, plastics, etc., on nonferrous metal substrates eg. aluminum, brass, stainless steel, copper, titanium, etc. |
