The E+E EE820 CO2 Transmitter is designed for use in harsh, demanding applications. A multiple point CO2 and temperature factory adjustment procedure leads to excellent CO2 measurement accuracy over the entire temperature working range, so the EE820 can even be installed outdoors.

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 housing with a special integrated filter the EE820 can be installed in polluted applications such as in agriculture and live stock barns. For fast response time requirements there is an EE820 version with forced air circulation created by a fan installed behind the filter. An optional M12 connector facilitates easy removal of EE820 before site cleaning operations.

The measured data range of up to 10,000ppm is available on the voltage or current analogue outputs. An optional kit facilitates easy configuration and adjustment of the EE820.

Typical applications for the EE820 include:

• Greenhouses
  
• Fruit and vegetable storage
  
• Stables
  
• Hatchers and Incubators
  
• Vehicles, Trains, Trams
