N2O Wastewater Sensor

sensor technology for industrial applications

Stable, real-time signal

Temperature compensated data output

Only maintenance is a 10-minute calibration every second month

N₂O Wastewater Sensor

Measure dissolved N₂O with fast response time in the biological tanks of wastewater treatment plants

The sensor delivers a temperature compensated data output to your N₂O Wastewater Controller with a response time of less than 65 seconds. You can expect a very stable signal from the sensor. Read more...

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.

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.
