Environmental Monitoring Solutions
The TunnelTech 602 Illuminance photometer monitors the average illuminance within a tunnel in accordance with Commission Internationale de l´Eclairage, (C.I.E.), publication 88, 1990 recommendations, the photometer monitors the average illuminance over a range of 0 – 20,000 lux.
The detector is a metal/glass-encased silicon diode photocell that is filtered to give a response that mimics the performance of the human eye. The detector is perfectly linear within its measuring range and has an instantaneous response to changing light levels.

The TunnelTech 305 Air Flow Monitor (AFM) is CODEL's industry proven tunnel air flow monitor.
The TunnelTech 400 analyser electrochemical cell technology determines CO, NO NO2, SO2 or O2 concentrations. With no moving parts, reliability levels are extremely high and maintenance requirements are very low.
The TunnelTech 205 NO2 Air Quality Monitor is a highly efficient transmissometer configured for the continuous measurement of Nitrogen Dioxide in road tunnel atmospheres.
The TunnelTech 201 Air Quality Monitor is an essential part of any road or rail tunnel safety system. Firstly, it monitors the atmosphere within the tunnel and 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 201 analyser uses well proven infra-red techniques to determine CO and NO concentrations and optical attenuation to monitor visibility levels. As there is only one moving part, reliability levels are very high and maintenance requirements are extremely low.
The TunnelTech 202 Air Quality Monitor continuously monitors CO, & Visibility and is an essential part of any road or rail tunnel safety system.
