X-Ray Fluorescence Gauges are used to measure coatings
containing quantities of metal or heavy elements, on plastic or
paper substrates. The sensor energy level is selected for the
application, such that the photons striking the material cause it
to fluoresce. The returned fluorescence energy provides the
information necessary to precisely calculate the coatweight. This
selective technique has significant advantages in simplicity of
operation, accuracy, and reduced equipment costs.
The Model 105 and Model 107 X-Ray
Fluorescence Gauges provide an accurate way to measure thin, high
atomic number coatings on non-metallic films. By tuning the
sensor to the required fluorescence energy, it is possible to
detect thin coatings of Zinc, Iron Oxide, Silver, or a variety of
other high atomic number coatings (see list for each gauge below).
Typically the sensors can measure coatings in the range of 0 gsm to
25 gsm.
