A magnetic pull-off gauge (type I) is a measurement device used to determine the thickness of a coating without damaging it. The magnetic pull-off gauge does this by measuring the magnetic attraction between the iron-based (ferrous) material that has been coated and a magnet that is attached to the… View Full Term
