Measuring Method

The E E CO2 sensors feature the dual wavelength/dual detector NDIR principle. One detector is tuned to 4.2 µm wavelengths, which is absorbed by CO2, the second detector on 3.9 µm, which is not affected by any gas. For every single measurement the CO2 concentration is calculated from the outputs of the two detectors.

This procedure is highly insensitive to pollution and appropriate for both HVAC and demanding applications.

A multiple point CO2 and temperature adjustment procedure leads to excellent CO2 measurement accuracy over the entire temperature working range.

Several E E CO2 measuring devices feature also temperature and humidity measurement.
