N₂O Wastewater Connector Unit 3.0

Screenless calibration with LED guidance

Calibration is guided step by step through LED signals on the Connector Unit. You initiate calibration, set zero point, and complete reference measurements by following clear visual cues.

You interact directly with the sensor and follow a simple, structured workflow without navigating menus or using external tools. This allows you to perform calibration where the sensor is installed, without additional equipment or interfaces.

Connect and integrate

The Connector Unit links sensors to the Operator Console and enables communication across the system. You can connect up to 2 sensors to each Connector Unit, and connect multiple units to 1 console.

Connector Units can be installed close to the sensors and linked together, allowing you to cover larger areas of the plant with a flexible cable setup. This makes it possible to route cables around tanks and structures and place and move sensors to where they provide the most value.
