    The E+E dual wavelength NDIR CO₂ sensor compensates for aging effects, is highly insensitive to pollution and offers outstanding long term stability. A multiple point CO₂ and T factory adjustment leads to excellent CO₂ measurement accuracy over the entire T working range.

    EE800 with analogue outputs features an optional passive T sensor, while EE800 with digital interface (Modbus RTU or BACnet MS/TP) calculates additional physical quantities: absolute humidity, mixing ratio, enthalpy, frost point temperature and water vapor partial pressure.
