Abstract
A magnetic thickness gauge is disclosed wherein a balance arm is pivotally mounted in a housing with a spring providing a bias force to counteract a magnetic attraction of the balance arm toward a base of a coating to be measured. The balance arm is provided with a probe assembly including a magnet selectively positionable with respect to a spherical contact member of either a particular alloy of aluminum, iron and silicon or of tungsten carbide. The housing is preferably provided with supports at either end of the gauge. A balance arm is moved by way of a protrusion provided between the probe assembly and an adjustment knob for the spring with a scale and pointer indicating the thickness of the coating to be measured.
