Description

Reliable H2S insights
The SulfiLoggerTM H2S sensor provides reliable insights into your H2S challenge by continuously measuring H2S directly in raw wastewater and in the air above. These unique insights – among other applications – enable you to pinpoint target areas for further H2S mitigation, to permanently monitor critical hotspots, or to control chemical dosing stations.

 

Measure H2S anywhere in sewer networks or at treatment plants
Built to withstand the harsh conditions found in sewer networks, the SulfiLoggerTM sensor is designed to operate under anaerobic conditions and in up to 100% humidity. It is suitable for both permanent H2S monitoring and portable sulfide mapping campaigns in the entire collection system and at wastewater treatment plants.

 

Data anywhere, anytime
The SulfiLoggerTM sensor delivers continuous data directly into existing SCADA/PLC systems in real-time using an analogue 4-20mA output, while the PowerCom Box accessory enables cloud data and battery-powered operation, effectively transforming the sensor into a self-contained sensor system that can operate in locations without SCADA connectivity.
