X-ray fluorescence (XRF) detector
NDC Infrared Engineering

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.
