The model AF45 is a single channel Ultraviolet (UV) absorption sensor with a lamp compensation reference channel. The sensor is designed for inline operation and provides extremely accurate concentration measurements with great repeatability, linearity and resolution. The AF45 can be used for HPLC control, detection of aromatic compounds, organic load, protein concentration and other demanding applications.

The light intensity of the low-pressure mercury lamp itself is measured by a second hermetically-sealed silicon photo diode and compensates for any lamp intensity variations. This assures the highest level of precision and long-term performance.

The single crystal sapphire optical window provides superior resistance to all abrasive and corrosive media. The AF45 comes with a broad variety of line sizes, process connections and wetted materials and can be adapted easily to the process. NIST-traceable validation accessories provide absolute measurement confidence.
