Are Ammonia Sensors Ready for Outdoor Use?

ABSTRACT: Ammonia (NH₃) gas is primarily an agriculture atmospheric pollutant, and measuring near-emission sources is essential for understanding NH₃ emission plumes. Sensors in theory are attractive alternative monitoring methods due to their high-time data resolution, size, and lower costs; however, there are metrological and technical challenges. NH₃ sensors operating in the subppm range (typical of near-emission source concentrations) are relatively new to the market, and while promising, there are metrological and technical challenges, especially in outdoor environments. Six NH₃ sensors were evaluated under field conditions at a poultry house emission simulation site, Whim Bog, Scotland (3.4 g of NH₃ min^-1). Five electrochemical
