Tunnel Sensors - Model ECOM - Electrochemical CO Monitor for Tunnel

by Tunnel Sensors Limited

The ECOM tunnel monitor measures the concentration of carbon monoxide (CO) within an ambient environment such as road, rail, meteorological or other industrial application. These measurements can be used as part of an air quality management system for ventilation control and/or secondary smoke detection within a traffic tunnel or other confined ...

TunnelCraft - Model III - NO2 Air Quality Monitor (AQM)

by Codel International Ltd

Nitrogen dioxide (NO2) is fast becoming the most important measurement in tunnels and will eventually replace nitric oxide (NO) as the key measurement. The TunnelCraft III NO2 Air Quality Monitor (AQM) uses a high-power blue LED to measure the attenuation of UV/blue light by NO2 in the tunnel atmosphere. The AQM consists of a transceiver that ...

Tunnel Sensors - Model VCOM - CO and Visibility Monitor for Tunnels

by Tunnel Sensors Limited

The VCOM tunnel monitor measures the concentration of carbon monoxide (CO) in tunnel atmospheres and makes a visible opacity measurement to determine the visibility within the tunnel. These measurements can be used as part of an air quality management system for ventilation control and/or secondary smoke detection within a traffic tunnel or other ...

Tunnel Sensors - Model VNOX - NO2 and Visibility Monitor for Tunnels

by Tunnel Sensors Limited

The VNOX tunnel monitor uses differential optical absorption to measure nitrogen dioxide (NO2) in tunnel atmospheres and makes a visible opacity measurement to determine the visibility within the tunnel. These measurements can be used as part of an air quality management system for ventilation control and/or secondary smoke detection within a ...

TunnelCraft - Model 4 - Air Flow Monitor (AFM)

by Codel International Ltd

The Air Flow Monitor (AFM) uses ultrasonic technology to measure air velocity. A single transmitter and an array of four receivers are contained in the measuring head. Air velocity and direction are calculated from measurements of the phase shifts from the ultrasonic signals at the receivers. The sensor is compact, contains no moving components, ...

TunnelCraft - Model III - Visibilty Air Quality Monitor (AQM)

by Codel International Ltd

The TunnelCraft III Visibility Air Quality Monitor (AQM) uses visible light channels to measure the visibility within a tunnel environment. The AQM consists of a transceiver that projects visible light to a reflector unit mounted 3m away. The reflected light is received by the transceiver and the specific absorption is measured to determine the ...

Tunnel Sensors - Model AIRFLOW - Air Velocity and Direction Monitor for Tunnels

by Tunnel Sensors Limited

The AIRFLOW tunnel monitor uses proven ultrasound technology to measure the speed and direction of air movement within the tunnel environment. These measurements can be used as part of an air quality management system for ventilation control wihtin a tunnel or other confined space including traffic tunnels, rail tunnels, cable tunnels as well as ...

TunnelCraft - Model 4 - CO/VIS Air Quality Monitor (AQM)
