EM500 CO2


Available on backorder

EM500-CO2 is designed for measuring gaseous carbon dioxide (CO2) concentration in harsh environments. It is useful in the application where knowing CO2 level is important like greenhouse, building ventilation, fruit and vegetable storage. Besides, it also supports temperature, humidity and barometric pressure measurement.Milesight EM500 CO2 Sensor (4 in 1)

Smart Wine Cellar

Carbon dioxide is a by-product produced during the fermentation of wine. Because the density of carbon dioxide is heavier than air, it is easy to overflow from the fermentation tank. When it falls on the ground of the winery, it will form fatal and undetectable potholes, which will bring great hidden danger to the safety of the operators.


Forest Fire Detection

Nowadays, forest fires often cause serious threats to the environment and produce real emergency situations and natural disasters. Most of the times, when someone notices about the fire, it is too late because the fire has spread already. Thus, the enhancement of forest fire detection system by CO2 (carbon dioxide) monitoring can be evaluated.
