CO₂ Sensor for Demanding Applications

EE820

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.
