Tunnel Air Quality Monitors

Comprehensive Multi-Parameter Atmospheric Safety

Tunnel Air Quality Monitors provide a holistic, real-time picture of subterranean environmental health. Utilising highly stable infrared gas cell correlation, advanced electrochemical cells, and optical transmitivity, these multi-channel systems (such as the TunnelTech 201, 700, and 900 series) continuously quantify critical hazards like CO, NO, NO2, SO2, and visibility in a single compact enclosure. With robust IP65/IP66 or IP69K rated housings, these monitors dynamically command the ventilation system to flush out dangerous emissions without suffering optical drift from airborne tunnel contaminants.
