CO2. E+E''s years of experience in sensors and thinfilm technology lead to highest quality nondispersive infrared (NDIR) CO2 measuring cells. The cells with goldplated light path are assembled in stateoftheart clean rooms and represent the prerequisite for highly accurate and long term stable CO2 measurement. More about CO2

These sensors start off correct but gradually lean towards the extreme. Meaning, your voc and co2 (especially voc) will never get back to the original calculation once its been effected by any variable. Lets say VOCs were at 120 to start. You cooked one day and level went to 500. After you air the house out, new default is 150.

27/7/2017· The switch operates very simply. Inside the sensor housing is an LED and a phototransistor. When the sensor tip is in air, the infrared light inside the sensor tip is reflected back to the detector. When in liquid, the infrared liquid is refracted out of the sensor tip, …

1/7/2021· Because carbon monoxide is slightly lighter than air and also because it may be found with warm, rising air, detectors should be placed on a wall about 5 feet above the floor. The detector may be placed on the ceiling. Do not place the detector right next to or over a fireplace or flameproducing appliance. Keep the detector out of the way of ...
