CO2 sensor for demanding applications

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.

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.
