Product description
The Sulfimax GX online GAS was developed for the continuous and precise determination of hydrogen sulfide (H2S) in gas mixtures.
The system is designed to measure both very high H2S concentrations from 100 to 20,000 ppm and low concentrations near the odor threshold from 0.1 to 100 ppm. An integrated dilution stage provides maximum flexibility during operation.
Equipped with a selective amperometric sensor featuring gas-selective membranes, diaphragm pumps for gas transport and sample aspiration, and an integrated PC, the Sulfimax GX online GAS ensures continuous recording of measurement data, trends, and alarm conditions.
Measurement results are easily transmitted to the control room or process control system via digital (alarm) and analog outputs.
Thanks to automatic purging circuits, the Sulfimax GX online GAS enables drift-free gas analysis, even in oxygen-free gases such as biogas. The gentle operating mode significantly extends sensor service life.
Designed for wall mounting and equipped with purification stages, the Sulfimax GX online GAS also provides a reliable basis for H2S-adapted control of enrichment gas processes.
In addition, the device is also available for monitoring ammonia (NH3), sulfur dioxide (SO2), or ozone (O3).
Key Features:
- Continuous monitoring of H2S in gas mixtures
- Wide measuring range: 0.1 to 20,000 ppm
- Integrated dilution stage for flexible analysis
- Long sensor lifetime due to gentle operation
- Drift-free measurement, even in oxygen-free gases
- Digital and analog signal outputs for system integration
- Also available for monitoring NH3, SO2, and O3
Applications
- Online recording of the current H2S gas concentration as a basis for H2S-adapted controls (e. g. pump sump, gravity lines, collection tanks)
- Biogas processes, fermentations
- Environment analysis
- Wastewater analysis
- Landfill leachate monitoring
Advantages
- Fully automated sample dosing
- Hardly any cross-sensitivities due to selective electrochemical sensor
- Output 4 to 20 mA for integration of the H2S signal into the local control system
- Long sensor life due to intermittent gas path gas path switching
- Active sample aspiration, thus free installation (wall mounting) with up to 100 m distance from the sampling point
Features and Results
- Continuous H2S gas analysis (measuring time under 5 min)
- Robust analysis method (drift stability)
- Simple calibration
- Simple, clear software
- Integrated purging steps to ensure a constantly updated sample for analysis
- Also available for measuring ammonia (NH3), sulphur dioxide (SO2) or ozone (O3)
