CO₂ Sensor for Demanding Applications

Open Link in Lightbox
  • CO₂
  • Temperature


The EE820 measures reliably CO₂ concentration in harsh, demanding applications. A multipoint CO₂ and temperature factory adjustment leads to excellent accuracy over the entire temperature working range.

  • EE820 CO₂ sensor for wall mounting

    The EE820 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.

    With its robust, functional IP54 enclosure and a special filter, the EE820 is suitable for polluted applications such as agriculture and livestock barns. The M12 connector facilitates the removal of the device before site cleaning operations. An optional kit allows for easy configuration and adjustment of the EE820.

    Typical Applications

    • Greenhouses
    • Fruit and vegetable storage
    • Hatchers and incubators
    • Life stock barns

    Not at all. Do not temper in any way with the CO₂ sensing cell. Please see the operation manual of the specific E+E CO₂ measurement device.

    Please the section "Maintenance" in the operation manual.

    All E+E CO₂ measuring devices feature an auto-calibration function. For details please refer to "Principles of CO₂ measurement".

    Transmitter with "two-wire" technology receive the power from the process, and the signal is carried on return wire (closed current loop). With "three-wires" technology the power supply is separate from current output: 2 wires are the power supply and the third carries the signal.
