E+E's years of experience in sensors and thin-film technology lead to highest quality non-dispersive infrared (NDIR) CO₂ measuring cells. The cells with gold-plated light path are assembled in state-of-the-art clean rooms and represent the prerequisite for highly accurate and long term stable CO₂ measurement.
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 industrial process control.
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, humidity and barometric pressure measurement.
