NH3 Analyzer

NH₃ Measurements Made Simple

Ammonia (NH₃) is the most prevalent alkaline gas in our atmosphere, making it the main focus of atmospheric chemistry, air quality, air visibility, and ecosystem processes.

Our optical ammonia analyzer (OAA) with <1ppb (1sec, 1σ) precision is an ideal solution for ambient air quality monitoring, elucidation of particulate matter formation, livestock emissions quantification, vehicle emissions quantification, indoor air quality, and soil flux measurements.
