Technical Data
N2O Wastewater Controller

Direct Data Collection and Transmission

With the N2O Wastewater Controller, you collect data from the N2O Wastewater Sensors. You can connect the controller to your plant's PLC or SCADA system to automate the collection of data. You can also choose a USB data logger to extract data directly from the controller to a USB drive without connecting to the PLC or SCADA system.

Connect up to two sensors

You can monitor the nitrous oxide levels and emission values from up to two sensors on the controller and adjust the settings with the TFT touch screen.

We have set up standard fixed model parameters to calculate the emission levels in the controller. If you require more accurate emission values, you can add an emission module with dynamic input parameters.

Autozero feature

From 1 October 2023, the N2O Wastewater Controller is equipped with Autozero. The Autozero feature aims to ensure that negative values do not impact your emissions reporting by performing an automatic zero point calibration. So you can rest assured that the sensor is performing as planned, and your nitrous oxide emissions reporting will benefit from precise, correct, and clean data.

Sensor calibration

When you perform the sensor calibration every second month, you simply access the controller’s system menu onsite and follow the N2O Calibration Kit manual and/or the N2O Calibration video guides.

Mounting the N2O Wastewater Controller

You will receive the controller with a mounting plate as standard. You can add a pipe mounting kit and a weather protection canopy depending on where you place the N2O Wastewater Controller.
