Carbon Dioxide (CO2) absorbs the wavelength within the infrared portion of the electromagnetic spectrum. An IR emitter then directs the infrared light through a sample of the growth chamber''s atmosphere, then through an interferometer filter that isolates the proper wavelength and finally allows the sensor to process the data.

All carbon dioxide sensors need calibration. Depending on the application, this can be accomplished by calibrating the sensor to a known gas or using the automatic baseline calibration (ABC) method. Both have pros and cons you should know. Most of our CO2 products use nondispersive infrared (NDIR) carbon dioxide sensors.
There are two primary types of CO2 sensor in the METTLER TOLEDO portfolio. For bioreactors and pharmaceutical production, the InPro 5000i is a dissolved CO2 probe that provides realtime CO2 values based on the technology of the Severinghaus principle, which utilizes the correlation between dissolved carbon dioxide and pH of a liquid. The sensing electrode is an enhanced pH electrode separated ...
