N2O Wastewater Sensor

Fast responding and reliable nitrous oxide measurements

The real-time signal from the N2O Wastewater Sensor makes it possible for you to implement active control strategies to minimize your plant's climate footprint.

The only maintenance required from you is a calibration every second month. This will take you around 10 minutes. You can check out this instruction video to see how to calibrate the sensor.
