How to calibrate a CO2 sensor? - Yoctopuce

May 01, 2015· Zero calibration of the Yocto-CO2. To circulate the gas into the sensor, set a small tip with a external diameter in one of the two openings on top of the sensor, as is the above picture. Circulate the gas at a litre/min speed for about two minutes, that is one minute more than the time necessary for the measure to stabilize.
