H2S sensor for rough environments

Measure H2S anywhere

Get the right H2S insights with full time-resolution and no need for manual sampling.

Reliable insights in rough environments

SulfiLogger™ H2S sensor

The SulfiLogger™ sensor continuously measures H2S directly in wastewater, air, and inline in process gases. The sensor provides reliable insights that empower you to adopt a data-driven and proactive approach to odor and corrosion control in Wastewater, Biogas, and Oil & Gas industries.

With the SulfiLoggerTM H2S sensor you can:

  • Measure H2S almost anywhere in rough environments

  • Keep track of all changes in H2S levels

  • Avoid complex sample conditioning systems

Industries

H2S sensor solutions for any industrial application
Wastewater

Measure H2S directly in untreated wastewater to get reliable insights unaffected by flow, ventilation or turbulence.

Biogas

Monitor H2S continuously in wet biogas immediately after the anaerobic digester or desulphurization processes.

Oil & Gas

Measure right after the oil & gas separator to follow the development in H2S and to eliminate the need for manual sampling.

Benefits

Data-driven and proactive odor and corrosion control

With the SulfiLoggerTM H2S sensor’s reliable insights, you can:

Are your assets deteriorating faster than expected due to H2S-induced corrosion?

Map your network with a group of H2S loggers and implement a data-driven asset management strategy to extend the remaining lifespan of your valuable pipelines, wells, engines, and other assets.

Are you troubled by frequent odor problems?

Locate H2S hotspots in the network with the H2S monitor and prioritize mitigation initiatives to prevent rotten-egg malodors and time-consuming residential complaints handling.

Are you dosing scavenger chemicals in excess to prevent H2S odors and corrosion?

Optimize existing chemical dosing strategies or adopt new semi- or fully automated dosing strategies using the SulfiLoggerTM probe’s real-time H2S data as a direct and dynamic control input for chemical dosing pumps.

Do you know the exact source of where your H2S problems originate?

Map hotspots in complex sewer networks to locate the root cause of H2S challenges and solve the problem at the source. The H2S device is suitable for both permanent and portable measurement campaigns.

H2S impedes biological wastewater treatment processes and negatively affects the yield in Biogas production.

Control and optimize your processes with real-time sensor data from the H2S logger.

How safe is safe enough?

H2S causes several negative health effects and is potentially lethal at concentrations above 500ppm. Detect peak loads in your H2S development and improve your worker safety.

Measuring H₂S shouldn’t be complicated.

Many traditional sensors and analyzers rely on complex gas conditioning systems to remove moisture and impurities before measurement.
The SulfiLogger™ sensor eliminates this need by measuring H₂S directly in raw gas streams. This simplifies installation, reduces maintenance, and provides reliable data without the hassle of additional equipment.
