Alphasense now provides a solution to some old problems:
· Palmes-type diffusion tubes are commonly used for indicative measurement of nitrogen dioxide (NO2) in cities for Local Air Quality Management. But sampling over several weeks gives only one average concentration for the entire sampling period and the result is reported weeks after the measurement.
· Odours which were previously ignored by local industry and city councils are now headline problems. There is a growing requirement to monitor odour plumes around landfills, waste water treatment plants, agricultural/ poultry farms and industrial sites- but the cost of the necessary network of monitoring nodes is prohibitive. Hydrogen sulfide (H2S) or ammonia (NH3) are the two mot commonly measured gases for odour detection.
Alphasense introduces the Electronic Diffusion Tube (EDT): a single gas data logger with ppb resolution using the proven Alphasense A4 family of electrochemical ppb gas sensors.

EDT-01 Electronic Diffusion Tube Applications include:
· Co-locating with Palmes-type diffusion tubes to record diurnal and weekly patterns and peaks
· Monitoring urban construction sites for compliance, especially for peak concentrations
· Ring-fencing odour sources for plume monitoring- daily downloads provide regular feedback
· Tracking ammonia plumes on poultry farms
· Detecting fugitive emissions from industrial sites for both leak detection and ensuring compliance
· Low cost educational tool when teaching about air quality
