Measuring method. The E+E CO2 sensors feature the dual wavelength/dual detector NDIR principle. One detector is tuned to µm wavelengths, which is absorbed by CO2, the second detector on µm, which is not affected by any gas. For every single measurement the CO2 concentration is calculated from the outputs of the two detectors.
Most of our CO2 products use non-dispersive infrared (NDIR) carbon dioxide sensors. These rely on an infrared light source and detector to measure the number of CO2 molecules in the sample gas between them. Over many years, both the light source and the detector deteriorate, resulting in slightly lower CO2 molecule counts. The industry calls this "drift". To combat sensor drift, during ...
The sensor is 12Vdc powered from the ALS3 which displays the CO2 level in PPM and interlocks to the gas supply in the kitchen. The gas supply is shut down when a high level of CO2 is detected ensuring a safe working environment. The NDIR CO2 sensor should be mounted in a dry area on a wall or pillar at head height approximately 2 – 3 metres ...
Co2 only consists of % of the atmosphere meaning; it’s a trace gas that’s quite difficult to detect. The Atlas Scientific EZO-CO2 sensor is a compact Non-Dispersive Infrared (NDIR) sensor that gets right to the point, giving you the Co2 readings in ppm.
