The E+E EE870 Modular CO2 Transmitter is designed for easy integration into OEM equipment for demanding applications. The interchangeable CO2 probe incorporates the dual wavelength NDIR CO2 sensor, which compensates for ageing effects, is highly insensitive to pollution and offers outstanding long term stability. Multiple point CO2 and temperature adjustments lead to excellent measurement accuracy over the entire temperature working range, ideal for use in agriculture and outdoors.

The IP65 enclosure of the probe and the replaceable PTFE filter offer excellent protection in harsh, polluted environments. The compact size, the M12 connector and the optional mounting flange allow for fast probe installation or replacement. An optional kit facilitates easy configuration and adjustment of the probe.

The measured data range of up to 5% CO2 (50,000 ppm) is available on the analog outputs of the conversion board. Several voltage and current ranges can be selected with jumpers. Additionally, the data is available on the Modbus RTU interface, which can be configured by the user with DIP switches on the board.

Applications for the EE870 include:

  • Greenhouses and livestock barns
  • Fruit and vegetable storage
  • Hatchers and incubators
  • Outdoor CO2 monitoring
