N2O Wastewater Controller

N2O Wastewater controller - nitrous oxide levels and emission rate 

The N2O Wastewater controller is operated through the TFT-touch screen and can take input from 2 N2O Wastewater Sensors. 

The controller displays temperature compensated N2O levels, emission rates and process temperatures from both sensors. 

The controller can be delivered with an optional USB data logger, making collection of data available without connecting to the PLC/SCADA system.


N2O Wastewater Controller is easily operated and displays nitrous oxide production and emission.
N2O Wastewater Controller displays both nitrous oxide levels and emission values.
The Controller can take input from 2 N2O Wastewater Sensors

Emission levels are calculated in the controller with the use of standard fixed model parameters. For more accurate emission values,dynamic input parameters can be used with the add-on emission module.

The recommended bimonthly sensor calibration is done onsite through the controller’s menu system and by following the calibration manual that comes with each N2O Calibration Kit.
The controller comes standard with a mountingplate and can be ordered with additional pipe mounting kit and weather protection canopy.
