Road Tunnel Air Quality Monitors

The Tunnel Air Quality Monitor by Codel is an essential part of any road tunnel safety system. It uses infra-red techniques to determine CO and NO concentrations and optical attenuation to monitor Visibility levels. It also monitors the atmosphere within the tunnel and ensures that the ventilation system provides sufficient clean air to protect tunnel users' health and for drivers to see the road ahead clearly.
