Tunnel Emissions Monitoring

TunnelTech 100 Series Sensors are an essential part of any road or rail tunnel safety system. Firstly, it monitors the Visibilty within the tunnel and ensures that the tunnel ventilation system
provides sufficient clean air for drivers to clearly see the road ahead.

The TunnelTech 200 Series Air Quality Monitors can continuously monitor CO, NO & visibility within road and rail tunnels. Monitoring of these vital gases ensures that the tunnel ventilation system provides sufficient clean air to protect tunnel users health and for drivers to clearly see the road ahead.

The TunnelTech 300 Series Air Flow Monitors (AFM) are CODEL’s industry proven tunnel air flow monitors that combine the reliability of ultrasonic technology and delivers superb accuracy and reliability at a very competitive price.

The TunnelTech 500/700 Series use electrochemical cell technology to determine CO, NO & NO2 concentrations within road and rail tunnels. As there are no moving parts, reliability levels are very high and maintenance requirements are low.

The TunnelTech 600 series light monitors are CODEL’s industry proven llumiance and illuminance monitors for detecting light both inside and at the entrance of the tunnel.

The TunnelTech 801 flow monitor has been specifically designed for road, rail and civil tunnel and ventilation shaft applications and represents the latest in compact ultrasonic sensor-head design.
