CO₂, RH and T Duct Mount Sensor
EE850
The EE850 is a 3 in 1 duct mounted transmitter ideal for demand controlled ventilation and building automation. It combines CO₂, humidity and temperature in an innovative and functional enclosure. The EE850 incorporates the E+E dual wavelength NDIR CO₂ sensor, which compensates for ageing effects, is highly insensitive to pollution and offers outstanding long term stability.
EE850 CO₂, humidity and temperature sensor for duct mounting
The multi-point CO₂ and temperature factory adjustment leads to an excellent CO₂ measurement accuracy over the entire temperature working range.
An optional adapter facilitates easy configuration and adjustment via the EE850 service interface.
