Full sensor system
The kit is a fully self-contained sensor system ready to be deployed virtually anywhere in the sewer network, and suitable for a range of applications including permanent monitoring, root cause analysis campaigns or chemical dosing control operations.


Designed to stay in the sewer
The SulfiLogger™ sensor is designed to operate under extreme conditions and measures under anaerobic conditions and in up to 100% humidity. Unlike other measurement solutions, the sensor does not need regular dry-out time in office-like conditions. It is designed specifically to stay in the sewer.


4-20mA data, always
This sensor system delivers a continuous sensor signal into SCADA/PLC systems using the analogue 4-20mA output, while the sensor is powered by loop power from the same cable. This kit is also available in a configuration with cloud data and battery-powered operation.


This sensor system is a bundle containing multiple individual products.
