nitrate nitrite BOD COD with 1 sensor simultaneously

TriOS spectral UV sensor for nitrate and nitrite, and other components
OPUS is the new generation of spectral sensors for the online measurement of nitrogen and carbon compounds. Full spectrum analysis enables the OPUS to provide reliable measurements for NO3-N, NO2-N, organic ingredients (CODeq, BODeq, DOCeq, TOCeq) and a number of other parameters. Nitrate measurement is important on water treatment. We can adjust the path length of this sensor. This allows the nitrate, nitrite measuring range and detection limit to be adjusted. The system can work independently, but also via one of our transmitters. Optionally there is also the Nico from TriOS for only 1 parameter such as Nitrate or Nitrite.
