H2S detector for rough environments

Measure H2S anywhere

Continuously monitor hydrogen sulfide levels in wastewater, air, and process gases with the game-changing SulfiLoggerTM H2S detector – a robust device that delivers superior insights in rough environments.


X1 series detectors

Inline H2S detector for industrial applications

Measure H2S in extreme environments in wastewater, biogas, oil & gas, and other industries including aquaculture, pulp & paper, and industrial manufacturing.

Wastewater

Continuously measure H2S directly in wastewater for superior insights in sewer networks and at wastewater treatment plants.

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

Get the right H2S data, with no interruptions and minimal hassle, and take your odor and corrosion control strategy to the next level.

Get the right H2S data…

Measure H2S directly in untreated wastewater or wet gases for superior insights.

  • Measure in 0-100% humidity
  • Measure in wastewater, gases, or air
  • Measure in high temperature/pressure
…with no interruptions…

Get insights on any time scale to spot seasonal effects, daily patterns, and unexpected spikes.

  • Continuous data

  • Long-term data with no dry-out needed
  • Data in SCADA, in the cloud, or via RS-232
… and minimal hassle.

Get started and keep the detector’s high accuracy over time with minimal hassle.
