Typical Application: Wastewater Treatment & Landfill
In wastewater treatment plants, gases such as H₂S (from sludge digestion), NH₃ (from decomposition), and CH₄ (from anaerobic processes) pose explosion and toxicity risks. CO₂ can accumulate in enclosed spaces causing asphyxiation. MicMeta provides continuous personal monitoring for workers entering lift stations, digesters, headworks, and landfill gas collection areas. The man down alarm is critical for lone workers.
