Mini AQM systems contract from Leeds
University
Enviro Technology Services has won a five-way pitch for tender to supply four mini Air Quality Monitoring systems to Leeds University for a special traffic project starting in March 2006
Enviro Technology Services has won a five-way pitch for tender to supply four mini Air Quality Monitoring systems to Leeds University for a special traffic project starting in March 2006 Due to planning restrictions, Enviro Technology were faced with the challenge of designing a much smaller roadside station than traditional offerings

Latest air quality monitoring methods described
As part of a mission to become the leading authority on air quality monitoring and emissions, Enviro Technology Services will be holding a number of workshops at the MCERTS Conference on October 12-13
The ET Roadbox measures just 1m x 1m x 500mm.
Each contain a selection of B and K noise monitoring equipment, a Teledyne API M200E NOx analyser, a Teledyne API M400E ozone analyser - both MCERTS-approved - and a TSI superfine water-based particulate counter.
The Roadboxes will be used by the university's Institute for Transport Studies for an Engineering and Physical Sciences Research Council-funded project to gauge the impact of traffic on the local environment at one of the city's major road junctions.

The project will also involve meteorological monitors to determine wind speed and direction, traffic counter loops and automated numberplate recognition to identify the type and age of vehicles, plus the length of time it takes for each vehicle to negotiate the junction.
Dr Karl Ropkins, a research fellow in the Institute for Transport Studies, said the four Roadboxes will be monitoring the junction on the busy A660 Leeds-Bradford route round the clock over a four-year period.
He explained: "The project is intended to make a significant contribution towards current scientific understanding of the physical and chemical processes affecting the complex relationship between junction geometry, meteorology, traffic management and the resulting local environmental impact.
The four-year period was chosen because we needed a large data set to accurately represent conditions at the junction.
The results will be used in a series of research projects to look at the relationship between traffic in the area and its impact on the environment in terms of noise and pollution.
That data will then be used by the local authorities for the next level of models in the city's traffic management projects".
Dr Ropkins added that running such a high concentration of complementary monitoring equipment simultaneously would be demanding, but would "potentially provide a template for what both researchers and local authorities could be achieving across the country in the very near future".
Referring to the construction of the mini AQM stations, the Enviro Technology Services Operations Director Duncan Mounsor said: "There is a movement towards much more compact roadside stations.
Constructing the ET Roadboxes to the university's required dimensions was a challenge.
It's a very small footprint enclosure.
Despite their size, though, there is no loss of quality or functionality.
Unlike other roadside systems, ours uses individual, MCERTS-approved analysers - not shared components - so if one analyser fails the rest remain operational".
Duncan added that it was the superior technology that clinched the deal for ET following the competitive bid at the end of last summer.
"The superfine particulate analyser uses a laser system to measure water droplets.
Others used the solvent butanol, which has a nasty odour and requires specialist handling.".
