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.
Room, wall and duct mount CO2 sensors for demand controlled ventilation and process control. Available also with additional humidity and temperature outputs.
CO2 Sensors and Probes
CO2 Modules and Probes: compact, user configurable, low power consumption, temperature compensated and long term stable.
Room, wall and duct mount CO2 switches for demand controlled ventilation and process control.
CO2 Data Logger
Accurate recording of CO2 concentration along with humidity, temperature, pressure and electrical signals.
CO2 Hand-held Meter
Portable measurement of CO2, humidity, temperature and air velocity with interchangeable probes and data logging feature.
Wireless CO2 Sensors
High quality wireless transmitters for CO2, humidity and temperature 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 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.
