Theory of Operation
The gauge works on the principle of preferential absorption of near-infrared energy by the material being measured. Both the NIR wavelength where preferential
absorption occurs, as well as several non-absorbing wavelengths, are measured and compared to provide a precise calculation of coat weight or moisture content.
The NDC710 is based upon proven dual detector technology and therefore offers unsurpassed stability, essential for process control. An Auto Reference Standard option for allows easy, periodic checking of the
sensor performance.
The simplicity of use and minimal maintenance requirements, together with the renowned NDC Infrared Engineering optical system designed for operation in diverse ambient conditions, makes the NDC710 the reliable
choice for on-ine process measurements.
