EE872 incorporates the E+E dual wavelength NDIR CO₂ sensor, which automatically compensates for ageing effects, is highly insensitive to pollution and ensures an outstanding long term stability. The multi-point CO₂ and temperature adjustment leads to an outstanding measurement accuracy. The RH sensing element with E+E proprietary coating is suitable even for aggressive and corrosive environment.

Beside CO₂, the EE872 measures also relative humidity (RH), temperature and ambient pressure (p). Additionally, the devices calculated also the dew point temperature (Td).

The heated versions of the EE872 are suitable even for high humidity and condensing environment. The IP65 enclosure and the PTFE filter cap offer excellent protection in polluted environment. With a catalytic filter cap, the EE872 is also appropriate for applications with periodical H2O2 sterilization.

The CO₂ measured data is available simultaneously on the analogue voltage and current outputs. Depending on the EE872 version, the RS485 interface with Modbus RTU or BACnet MS/TP protocol offers also the RH, T, p, or Td data.

The free PCS10 Product Configuration Software together with an optional adapter cable facilitates the configuration and adjustment of the EE872.
