The E+E EE872 CO2 / RH / Temp / Pressure Probe is designed for use in harsh and demanding environment in agriculture, life stock barns, hatchers, incubators, green houses or outdoors. The EE872 incorporates the E+E dual wavelength NDIR CO2 sensor, which automatically compensates for ageing effects and is highly insensitive to pollution. 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 version of EE872 is suitable for high humidity and condensing environment. The IP65 enclosure and the replaceable filter offer excellent protection in polluted environment. With a special filter cap, the EE872 is also appropriate for applications with periodical H2O2 sterilization.
