Application
Thankyou for selecting the Duomo CellAir
monitor. It is designed to detect the presence of
carbon dioxide in the ambient air to protect people
in confined spaces. High concentrations of CO
confined spaces are dangerous, and may lead to
health problems ranging from headaches and
fatigue to asphyxiation and death. CellAir
audible alarm and visual indication which will
activate when CO
concentration reaches a pre-set
2
level. Detection of high levels of CO
activate a relay that could be used for a fan to
ventilate the confined space and reduce CO
concentration in the area. CellAir
used in CO
storage areas, breweries, wineries,
2
cellars, beverage dispensing areas and fast food
outlets.
