Carbon Dioxide Detector - PubMed

Although CO2 detectors ultimately measure exhaled CO2, there are design differences between some units. Detectors can be divided into quantitative and qualitative types. Qualitative detectors simply demonstrate the presence or absence of CO2. The most basic unit of this type is the colorimetric detector producing a color change as the gas flows through a litmus paper film in the airway circuit ...

Carbon Dioxide Detectors & Meters | Edaphic Scientific

Most CO2 detectors are delivered pre-calibrated yet require periodic calibration (you will need to check the manufacturer’s specs as this can vary from months to years). One set of models has Automatic Background Calibration (ABC) and provides a maintenance free option. Around 4am each night, the sensor detectors CO2 levels in the office and assumes it should be at 400ppm as there are no ...
