The coating thickness could be detected by a magnetic
way with a particular instrument called Magne-gage.
The lab is equipped with two magnetic instruments
both calibrated on the following band: diamagnetic
films on magnetic substrates.
Therefore they are suitable to detect e.g. zinc,
chrome, cadmium, phosphate coatings etc…..mainly
on iron or steels.
The mentioned instrument has a good sensibility
and it neither destroys nor partially damages the
analysed items.
