N2O Wastewater Sensor 3.0

Measure N2O directly in the liquid phase to optimize your wastewater treatment process and reduce your emissions.

The N2O Wastewater Sensor delivers stable measurements across aerobic, anoxic, and anaerobic zones, so you can follow both where N2O is produced and where it is reduced. The sensor is built to handle the harsh wastewater conditions where foam, condensation and fouling are part of normal operation.

The fully digital sensor stores calibration and sensor-specific data on the sensor, so you can move it or replace the sensor head without losing setup or history. Your measurement data is collected and handled through the Operator Console, giving you direct N2O emission results without additional programming or calculations.

Every 2nd month you calibrate directly at the tank in minutes using LED guidance, without manual temperature measurement or using a screen. The sensor continuously monitors its own status and alerts you when calibration or sensor head replacement is needed. Read more...

N2O Wastewater Sensor 3.0

Measure N2O directly in your process

Calibrate at the tank

Calibration is only needed every two months and can be completed in minutes. The quick calibration can be performed right next to the tank with just a bucket with 4 l  tap water and the N2O Calibration Kit.

The sensor has a built-in temperature sensor so you just need to follow the LED guidance from the N2O Wastewater Connector Unit.

Smart sensor operation

The sensor continuously monitors its own status and alerts you when you should calibrate or exchange the N2O Wastewater Sensor Head. This helps you stay on top of maintenance without manual checks and ensure continuous measurements.

Calibration and sensor-specific data are stored directly on the sensor, so you keep calibration, history and setup when moving the sensors or replacing sensor heads. Measurement data is handled through the N2O Wastewater Operator Console, where you get direct N2O emission results without additional programming or calculations.

Part of a flexible monitoring system

The N2O Wastewater Sensor works as part of a complete system with the Operator Console and Connector Units. You can connect up to 16 sensors to one system and integrate data directly with your PLC or SCADA without adding complexity, subscriptions, or mandatory cloud platforms.
