Description

The CODEL TunnelTech 401 NO2 CO, NO and Visibility Air Quality Monitor is a compact extractive analyser configured for the continuous measurement of four key parameters in road tunnels. This extremely stable and reliable monitor incorporates an LED to utilise the capacity of Nitrogen Dioxide to absorb UV and blue light to provide accurate readings in parts per billion. It also uses the same sampling system to monitor Visibility using a unique double sensor design.

Two Electrochemical cells are also added to the sampling cell to measure CO and NO, NO2 , CO, NO and particulate are produced naturally by the combustion processes within the internal combustion engine and are emitted from the exhausts of all types of vehicles.
