Signal solves location problems for Bradford MDC
Air pollution monitoring for most large cities and towns now involves monitoring for traffic hot spots. Typically NOx is the pollutant measured (and sometimes particulates), but often the location for these hot spots allows very little space to locate any equipment, let alone a large air quality monitoring station.
This was the problem facing City of Bradford Metropolitan District council when it approached Signal Ambitech in 2003. As well as the space problem, the sites are often in areas where they could be subject to graffiti and vandalism.
Signal, as an analyser manufacturer, was able to design a NOx monitoring system that not only met these criteria, being only 400mm deep and looking like a piece of street furniture, but also offered the benefits of its Ambirak multigas AQM system. StreetNOx, from Signal Ambitech, offers a compact and user-friendly solution to monitoring busy roadside locations. Its narrow profile and choice of paint finish provides minimum visual impact and the air-conditioned interior ensures dependable operation. Based on the Ambirak multi-gas AQM (Air Quality Monitoring) system, the StreetNOx offers a NOx only utilising the Ambirak chemiluminescence analyser (in fast switching mode) as approved by NETCEN (AEA Technology's National Environmental Technology Centre) or NOx & PM10/2.5 solution.
StreetNOx includes a data logger, paperless chart recorder and communications system to allow remote collection of AQM data over a GSM modem. The analyser outputs are sampled every second and one minute averages are transferred to the PC for permanent storage. Remote control and data handling is eased using the Ambidesk software package. Running under MS Windows", Ambidesk fully automates the collection, display and reporting of AQM data.
The StreetNOx, has now been installed at the Bradford location for over six months and continues to operate successfully in every aspect, Signal Ambitech reports.
