Model C Wet Film Thickness Gauge

• Accuracy certification available
• The scale is engraved directly on the measuring disk which is moved to the outside of the gauge and eliminates reading errors of parallax.
• The measuring disk is separated from a supporting disk by less than half the distance found in other gauges for similar use, which minimizes errors due to deviation from flatness of the supporting surface.
• All gauge markings are engraved rather than stamped to avoid strains in the gauge which could reduce gauge accuracy.
• Stainless steel surfaces of the gauge are highly polished to enhance gauge cleaning.
• The support surfaces of the concentric disks are designed to insure the best possible penetration to the coating support surfaces.
• Development of new "state of the art" jigs and fixtures insure production of each and every gauge to within the closest possible tolerance consistent with the best available tool and die metal working equipment.
• The gauge bearings are of special design to provide the lowest possible starting torque and to provide ease of cleaning by removal of one of the finger grips. Ball or roller bearings have been found to be unsatisfactory due to their sensitivity to cleaning solutions.
• The most modern type of three dimensional coordinate measuring machine with a resolution and repeatability equal to or better than 0.0001 inches is now used in the production and inspection of the gauges.

Whenever, wherever and however coatings are applied, the thickness of application is of paramount importance. If the film is too thin, the hiding power will be poor, and the substrate will show through. In addition, there will be a reduction in the protective capabilities of the coating.

If the coating is too thick, not only may there be a loss in intended physical properties, but there will be a reduction in coverage and a proportional increase in cost. The use of the Model C gauge will not only promote uniform application of the specified amount of coating material, but will also insure optimum designed results from the coating used at minimum cost.

Select the Model C gauge with the range which will accommodate the thickness to be measured between 10% and 90% of the gauge range. Grasp the gauge with the thumb and forefinger so that the gauge body is free to turn. Place the gauge on a freshly coated surface at a thickness position greater than expected and roll the gauge to a thickness less than expected.

The gauge may then be lifted and placed on another part of the surface and rolled in the opposite direction on the unused portion of the gauge. Examination of the outside eccentric disk will show thickness values at which pick-up of the coating has taken place and the average of these values may be taken as the true coating thickness.

A brand New ergonomic gauge handle is now available for the Model C gauge. It offers a very comfortable, precision grip handle that can be quickly and firmly attached to or removed from the Model C gauge. It is useful as an aid in aligning the gauge on the test surface.

When the gauge is used on a moving surface, the handle aids the user to keep his hand at a distance from such surface. It also may prevent the possibility of dropping the precision instrument onto a costly rotating roller.
