Outdoor air quality monitor TunnelTech 700

CONO2NO

The TunnelTech 700 is an advanced technology analyser which gives complete flexibility in the choice of measurement options. The TunnelTech 700 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 701 analyser electrochemical cell technology to determine CO, NO & NO2 concentrations and optical attenuation to monitor Visibility levels. As there are no moving parts, reliability levels are very high and maintenance requirements are low. The sight tubes have been designed to ensure that airborne dust and contaminants do not reach the optical windows and cause drift Features & Benefits Measure CO, NO, NO2 & Visibility in one compact sensor. Advanced electrochemical cell technology. Integrated display and keypad, no external computer required. Class leading NO2 measurement. Minimal maintenance requirements. Easy to calibrate.
