Air quality monitoring developed for the ISS used in closed enevironments on Earth 

The air quality of any manned spacecraft is monitored in order to safeguard the health of the crew and allow astronauts to respond rapidly to an accidental release of harmful gaseous contaminants or degradation of the environmental control and life support system. With the continuous inhabitation of the International Space Station (ISS) since 2000 and crew expeditions lasting typically up to 6 months, air quality monitoring grew in importance. A sensor system called Airgloss was developed, tested and rolled out on ISS by ESA astronaut Roberto Vittori during his third flight in 2011to monitor in real time the concentrations of major constituents such as Oxygen, Carbon Dioxide and Nitrogen, and trace contaminants, such as combustion products. Airgloss transferred the technology developed for ISS and adapted it for terrestrial use.
