Inline H2S monitoring in Biogas made easy

Eliminate the need for complex gas sampling systems in biogas and RNG applications, and adopt a simpler, more effective strategy for reliable hydrogen sulfide monitoring.

The SulfiLoggerTM H2S sensor provides:

  • Reliable, inline measurements in wet & unprocessed gas
  • Continuous H2S data in the SCADA system
  • Easy installation & low maintenance

X1-series sensors Ex approved for use in Zone 0 (ATEX) and Class 1 Div 1 Locations (HazLoc).

Hydrogen sulfide (H2S) in biogas and RNG is a critical challenge due to its corrosive nature and the high cost of desulphurization. Traditional measurement technologies struggle with wet gas streams, making it hard to optimize your process efficiently.

The SulfiLogger™ sensor offers a unique solution for H2S monitoring in biogas. Designed for direct installation in raw and unprocessed gas, it delivers continuous, real-time measurements of H2S – even in wet biogas – without the need for gas drying, filtering, or extensive conditioning.

Optimize desulphurization with better data

With accurate H2S data available at every stage of the biogas process, operators can optimize single or multi-stage desulphurization, reduce chemical usage, and cut operational costs. The sensor’s ability to monitor H2S levels directly in the gas stream helps minimize over-treatment and improve process efficiency.

Rugged design for demanding biogas environments

The SulfiLogger™ sensor is built to withstand harsh biogas conditions and maintain long-term stability with minimal maintenance. Its robust construction enables direct mounting in digesters, pipelines, or gas streams where traditional analyzers fail.

A simpler approach to H2S monitoring in Biogas

Reliable, inline H2S monitoring in biogas doesn’t have to be complicated.
With the SulfiLoggerTM H2S sensor, it isn’t.

Our solution

Direct, inline monitoring that feeds continuous data into the plant’s SCADA system.

The traditional solution

Complex sample conditioning setup using single or multi gaz analyzers with extensive gas preconditioning processes and labor-intensive maintenance.
