OPUS aero

UV spectral sensor for online measurement of nitrate and nitrite in wastewater aeration tank
OPUS aero is the new generation of spectral sensors for online measurement of nitrate and nitrite in wastewater aeration tank. By analyzing a complete spectrum, OPUS aero is able to provide reliable readings for either NO3-N only or NO3-N and NO2-N, depending on the calibration.
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.
WiFi connectivity allows laptops, tablets or smartphones to be easily used for control without any special application software or app installation.
