N2O Wastewater Sensor

Fast responding and reliable nitrous oxide measurements

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

10-minute calibration every second month

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

Monitor N2O emissions with the N2O Wastewater System

Construction of the N2O Wastewater Sensor

The sensor is made up of 3 parts:

Outside

An N2O Wastewater Sensor Body in a robust aluminum alloy which can be unscrewed for easy replacement of the N2O Wastewater Sensor Head.

Inside

An N2O Wastewater Sensor Head.
