VSI UAV-based Air Sampling Systems. Measuring the gas composition and/or isotopic signature of air, and particulate matter particles within, reveals crucial information about water use, carbon balance, greenhouse gas or volatile emissions and/or air pollutants. Making remote air sampling affordable to a large range of customers world-wide, Vienna Scientific Instruments offers two UAV-mountable air sampling systems to either sample whole air into evacuated vials (AS-110) or sorbent tubes (AS-111). The air samplers are scientifically tested and ready to be mounted on your medium-sized UAV - meeting the air sampling targets of your research or environmental monitoring projects.
