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".
