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.

The main difference is the hardware interface. The Modbus RTU protocol runs on RS485 Hardware while Modbus TCP/IP protocol on Ethernet hardware.
Not at all. Do not temper in any way with the CO2 sensing cell. Please see the operation manual of the specific E+E CO2 measurement device.

All E+E CO2 measuring devices feature an auto-calibration function. For details please refer to "Princibles of CO2 measurement".
The standard scope of supply of E+E CO2 sensors includes an inspection certificate according DIN EN 10204 - 2.2. For details on calibration certificates please see our white paper "Calibration and Traceability in Measuring Technology".
Accredited calibration certificate for CO2 is available upon request, please see our calibration website.
Transmitter with "two-wires" technology receive the power from the process, and the signal is carry on return wire (closed current loop). With technology "three-wires" the power supply is separate from current output: 2 wires are the power supply and third carry the signal.
