Description
UV spectral sensor for online measurement of nitrogen and carbon with a resolution of 0.8 nm/pixel.
OPUS is the new generation of spectral probes for the online measurement of nitrogen and carbon compounds. By analyzing a complete spectrum, OPUS is able to provide reliable readings for N-NO3, N-NO2, organic compounds (CODeq, BODeq, DOCeq, TOCeq) and a range of other parameters.
OPUS is equipped with the new TriOS G2 interface, which enables simple and fast sensor configuration using a web browser. Integration into existing process control systems and external data loggers has never been easier.
Using WLAN, a laptop, tablet or smartphone can then simply be used for control without the need to install special application software or an app.
