Air quality monitoring in Shangai Expo |
 An air quality monitoring network in the EXPO Park area in Shanghai was realized in April 2010 by Unitec s.r.l. for Shanghai EMC (Environmental Monitoring Centre). Seven units are installed around the EXPO area
 in the days immediately preceding the start of the event. The seven units continuously monitor the ambient air concentrations of CO, NO2, O3 plus temperature, relative humidity and pressure. The VPN connection between ETL3000 units and the remote data acquisition centre, ensures secure and continuous communications with real time data upgrading.
