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

by Codel International Ltd     based in Bakewell, UNITED KINGDOM

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 ...

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

by Codel International Ltd     based in Bakewell, UNITED KINGDOM

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 ...
