Road Tunnel Monitoring - TunnelCraft III NO2 Air Quality Monitor
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 projects the light beam to a reflector within a stainless steel tube mounted 1m away. Sintered filters in the measurement chamber allow gases from the tunnel atmosphere to diffuse into the chamber while inhibiting the passage of particulates.The NO2 sensor can be used as a stand-alone instrument or as part of a multi-point monitoring system.Codel International Ltd are one of the UK's leading suppliers of Road Tunnel Monitoring - TunnelCraft III NO2 Air Quality Monitor, for more information on Road Tunnel Monitoring - TunnelCraft III NO2 Air Quality Monitor please visit our website (www.codel.co.uk/tunnel_sensors_air_quality_monitors_products_craft_no2.htm) or call us on 01629 814351 and we will be happy to assist with your Road Tunnel Monitoring - TunnelCraft III NO2 Air Quality Monitor requirements.
