As part of a number of measures to improve air quality around Liverpool City five new air quality stations, complete with ‘reference method’ chemiluminescent Teledyne API T200 nitrogen dioxide analysers, which measure in real-time, were supplied and installed by Enviro Technology in city center locations in late October 2020. As part of an ongoing maintenance package, a 3-year service and support contract with ET was also agreed.

The five new air quality stations are located at: 

• Liverpool East – Liverpool Edge Lane
• Liverpool North – Liverpool Everton Valley
• Liverpool South – Liverpool Speke Road
• Liverpool Centre Roadside – Liverpool Lime Street
• Liverpool Centre Background – Liverpool Clayton Square

ET’s Account Manager for the council, Paul Norman comments “The five, Teledyne T200 NOx analysers are housed in compact roadbox enclosures making them ideal for busy walkways, being less intrusive than traditional larger enclosures. Enviro Technology were excited to be a part of this project as Liverpool City Council are fully committed to improving the air that we all breathe and are working with a vast range of partners to make that happen”.

Designed to show real-time measurements on a colour coded map, the website also provides historic data of user selectable hourly mean values for NO₂ / NOx at each location of the ET supplied air quality monitoring stations.

Supplied by Envitech Europe, the website also displays nearby monitoring station “Liverpool Speke” operated by the Department for Environment, Farming and Rural Affairs as part of the national Automatic Urban Rural Network (AURN).
