Modbus CO₂ probe for demanding OEM applications

The EE871 CO₂ probe from E+E Elektronik is designed for maintenance-free use in demanding OEM applications. The Modbus protocol permits easy retrieval and further processing of measurement values and facilitates simple integration into custom applications.

Highest measurement accuracy

The compact probe measures CO₂ concentrations up to 10,000 ppm. Thanks to the multipoint CO₂ and temperature adjustment, temperature compensation ensures excellent measurement accuracy over the entire operating range of -40... 60°C.

Excellent long-term stability

The CO₂ measurement cell of the probe is based on infrared technology (NDIR) and uses a dual-wavelength auto-calibration procedure. Thus, the EE871 is maintenance free and highly resistant to environmental influences. Ageing effects are automatically compensated, thus ensuring excellent long-term stability.

High resistance to pollution

The IP65 enclosure and the replaceable filter ensure optimal protection from contamination. Therefore, the EE871 can also be used in harsh environmental conditions.

Easy assembly

Its compact design, M12 electrical connector and optional mounting flange facilitate the installation or replacement of the CO₂ probe. 

Due to its very low power consumption, the CO₂ probe is particularly interesting for use in battery-powered devices such as data loggers, handhelds and wireless sensors. Other applications can be found, among others, in greenhouses, stables, fruit and vegetable storage facilities, hatchers and incubators.
