SulfiLogger™ S1/X1-1120 sensor

The SulfiLoggerTM S1-1120 sensor continuously measures hydrogen sulfide (H2S) directly in pressurized wastewater or in biogas.

Please configure your sensor’s measurement media and range.

Description

Reliable H2S insights
The SulfiLoggerTM H2S sensor provides reliable insights into your H2S challenge by continuously measuring H2S directly in pressurized wastewater or wet biogas. These unique insights – among other applications – enable you to cost-optimize desulphurization processes, protect assets from H2S induced corrosion, and keep H2S levels under constant surveillance.

Measure H2S anywhere
Built to withstand the harsh conditions found in pressurized sewer lines and gas producing facilities, the SulfiLoggerTM sensor is designed to operate under anaerobic conditions and in up to 100% humidity. It is suitable for installation directly in pressurized sewer lines and virtually anywhere in biogas plants, including right after anaerobic digester or before/after desulphurization equipment.

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.
