Sampling / UV, Paramagnetic / NOx, SO₂, O₂
Features
- Ensures high precision and minimal moisture interference in NOx and SO₂ measurements using UV Differential Optical Absorption Spectroscopy (UV DOAS)
- Enables individual NO and NO₂ measurements without the need for a NOx converter
- Uses a Paramagnetic O₂ sensor for semi-permanent sensor use
