The modular E+E CO2 transmitter EE870 is designed for easy integration into OEM equipment for demanding applications. EE870 consists of a CO2 sensing probe, a conversion board and a connection cable. 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. A multiple point CO2 and temperature adjustment leads to excellent measurement accuracy over the entire temperature working range, ideal for use in agriculture and outdoors.
The IP65 enclosure of probe and the replaceable PTFE filter offer excellent protection in harsh, polluted environment. The compact size, the M12 connector and the optional mounting flange allow for fast probe installation, replacement or removal during the cleaning of the site, for instance a stable or an incubator. With the optional radiation shield, the probe can be also installed outdoors.
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. An optional kit facilitates easy configuration and adjustment of the probe.
