Evaluating Infrared Carbon Dioxide Sensors for 21st ...

CO2 incubators, IR Sensor, Cell Culture Abstract In a cell culture incubator, carbon dioxide (CO 2) gas is provided to mimic mammalian physiological pH. Over the decades, different technologies have emerged to detect and control the amount of CO 2 gas entering the incubator, including older style constant flow, and popular thermal conductivity (TC) and infrared (IR) sensors. This article ...

Carbon dioxide sensor - Wikipedia

Carbon dioxide sensor. Not to be confused with Carbon monoxide sensor. A carbon dioxide sensor or CO2 sensor is an instrument for the measurement of carbon dioxide gas. The most common principles for CO 2 sensors are infrared gas sensors ( NDIR) and chemical gas sensors. Measuring carbon dioxide is important in monitoring indoor air quality ...

How does an NDIR CO2 Sensor Work? |

Like every IR gas sensor, the analyzer at Mauna Loa used the same basic principle for measuring CO2. It has an infrared light radiation source at one end of a gas sample tube and an IR detector at the other. The band of infrared radiation is very close to the absorption band of CO2. As a result, the amount of light radiation that is absorbed by the CO2 molecules is proportional to the amount of carbon dioxide in the gas sample. However, since low levels of CO2 …

Why does my CO2 sensor read zero after calibration?

The Carbon Dioxide IR sensor is calibration sensitive it needs to have a two-point calibration performed in the proper order. Zero calibration with 100% Nitrogen gas, zero air or any gas matrix that does not have CO2 to calibrate your baseline. Span calibration with 5000ppm (5%) CO2 gas. The 5000ppm Span value is the lowest span value that the sensor will calibrate properly to.

CO2 Sensor Calibration: What You Need to Know |

Where maximum accuracy is less important than cost, a CO2 sensor can be calibrated in fresh air. Instead of calibrating at 0 ppm CO2 (nitrogen), the sensor is calibrated at 400 ppm CO2 (outdoor air is actually between 350 ppm and 480 ppm in normal geographic locations), then 400 ppm is subtracted from the newly calculated offset value.
