NX7500 multi-parameter scanning UV sensors include a new generation of UV spectral probes for online-monitoring of nitrogen and carbon compounds. Due to their ability to execute a full spectrum analysis these sensors provide reliable and accurate measuring values for NO3-N, NO2-N, organic compounds as well as for several additional parameters. Typical applications are waste water treatment plants, environmental monitoring programs, drinking water control and industrial observations. Benefit from the real-time and reagent-free measuring method without any requirements for sample taking and sample preparation. In addition, the NX7500 multi-parameter scanning UV sensors are equipped with nano-coated detector windows and optional automatic cleaning for sustained performance quality. The factory pre-calibration enables immediate use from day one.
