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. For fast response time requirements there is an EE820 version with forced air circulation created by a fan installed behind the filter.
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.

All E+E CO2 measuring devices feature an auto-calibration function. For details please refer to "Princibles of CO2 measurement".
The standard scope of supply of E+E CO2 sensors includes an inspection certificate according DIN EN 10204 - 2.2. For details on calibration certificates please see our white paper "Calibration and Traceability in Measuring Technology".
Accredited calibration certificate for CO2 is available upon request, please see our calibration website.
Transmitter with "two-wires" technology receive the power from the process, and the signal is carry on return wire (closed current loop). With technology "three-wires" the power supply is separate from current output: 2 wires are the power supply and third carry the signal.
