H2S Monitoring

The measurement of hydrogen sulfide (H₂S) can be a challenge due to chemical reactions and contamination. The systems often require a lot of maintenance, still not giving reliable results.

The OPSIS DOAS system is different, and works excellent also in an environment with high levels of SO₂.

OPSIS offers two systems for hydrogen sulfide monitoring. The cross-stack system is designed for measuring high concentrations of H₂S, while the hot wet extractive system is more suitable for measuring low concentrations.
