The E+E dual wavelength NDIR CO2 sensor compensates for aging effects, is highly insensitive to pollution and offers outstanding long term stability. A multiple point CO2 and T factory adjustment leads to excellent CO2 measurement accuracy over the entire T working range.
EE800 with analogue outputs features an optional passive T sensor, while EE800 with digital interface (Modbus RTU or BACnet MS/TP) calculates additional physical quantities: absolute humidity, mixing ratio, enthalpy, frost point temperature and water vapor partial pressure.

The main difference is the hardware interface. The Modbus RTU protocol runs on RS485 Hardware while Modbus TCP/IP protocol on Ethernet hardware.
All BACnet products are tested at E+E. The BTL listed E+E products have been additionally tested by the BACnet Testing Laboratories.
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".
Yes, this in normal in several applications. It is the case for instance in new concrete buildings, due to the concrete carbonation effect. The calcium in the new concrete binds CO2 from the air.
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.
