EE850

The EE850 combines CO2 and temperature (T) measurement in an innovative enclosure. It is ideal for demand controlled ventilation and building automation. With a CO2 measuring range of up to 10 000 ppm and a T working range of -20...+60 °C (-4...+140 °F), the EE850 can be employed also in demanding climate and process control applications. The EE850 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.

The multi-point CO₂ and temperature factory adjustment leads to an excellent CO₂ measurement accuracy over the entire temperature working range.

An optional adapter facilitates easy configuration and adjustment via the EE850 service interface.

FAQ

Transmitter with "two-wire" technology receive the power from the process, and the signal is carried on return wire (closed current loop). With "three-wires" technology the power supply is separate from current output: 2 wires are the power supply and the third carries the signal.

All E+E CO₂ measuring devices feature an auto-calibration function. For details please refer to "Principles of CO₂ measurement".
