Sulfides are critical indicators in a wide range of industries — from environmental monitoring to chemical production and biogas plants.
High sulfide concentrations can cause corrosion, equipment damage, health hazards, and efficiency losses in production processes.
Accurate and fast determination of sulfide levels is therefore essential for quality control, process optimization, and regulatory compliance.
ECH offers innovative solutions for precise sulfide analysis in liquids and gases, enabling safe, efficient monitoring and process control.

Applications
- Online acquisition of the current sulfide concentration
- Waste water analysis for control systems (pump sump, free level or pressure water pipe)
- Landfill leachate monitoring
- Industrial sewage treatment plants
- Municipal sewage treatment plants
Advantages
- Automatic sample dosing
- Hardly any cross-sensitivities due to indirect method
- Output 4 - 20 mA for integration of the H2S signal into the control system
- Short measuring intervals allow fast reaction to changes
- Low maintenance requirements
Features
- Detection of the true H2S content directly in the liquid phase and thus independent of weather conditions (even in strongly basic samples)
- Simple calibration
- Simple, clear software
- No cross-contamination due to self-cleaning between measurements
- Long sensor life due to integrated regeneration processes
