TriOs OPUS UV Spectral (Nitrate, Nitrite, TSSeq, Organic [CODeq, BODeq, DOCeq, TOCeq])

UV spectral sensor for the online measurement of nitrogens and carbons with a resolution of 0.8 nm/pixel.

OPUS is the new generation of spectral sensors for the online measurement of nitrogen and carbon compounds. By analyzing a full spectrum, OPUS can deliver reliable readings for NO3-N, NO2-N, organic ingredients (CODeq, BODeq, DOCeq, TOCeq), and several other parameters.

OPUS features the new TriOS G2 interface, allowing fast and easy configuration of sensors by using a web browser. Integration into existing process control systems and external data loggers has never been easier.

With the optional battery pack, mobile applications are also feasible. WiFi connectivity allows laptops, tablets or smartphones to be easily controlled without special application software or app installation.
