Milesight CO2 Sensor 4in1 - EM500-CO2 Rayleigh They also have clear markingsThe Milesigh EM500 CO2 is designed for monitoring CO2 concentration, temperature, humidity and barometric pressure in outdoor scenarios. 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
