The Airyx WGA 020 provides long-term stable, real-time measurements of relevant greenhouse gas emissions from wastewater treatment plants along with minimal maintenance and calibration effort.
- Swimming sampling hood with metal cage system. Targeted and stable gas collection directly from the water surface, even in dynamic or harsh environments.
- Stabilised temperature. This ensures high accuracy and minimal drift under fluctuating environmental conditions.
- Continuous concentration measurements. Real-time monitoring of target gases with high temporal resolution for accurate process and emission control.
- Humidity-resistant analysers. Sample gas drying impedes humidity related sensor degradation.
- Heated sampling tube (optional) preventing condensation for loss-free gas transfer between sampling hood and analyser.
