Great for human respiration activities or the perfect complement to the CO2 gas sensor. Designed to measure oxygen concentration in air, the sensor’s range is 0 to 27% oxygen. For human respiration activities, the end of the sensor can connect to a 22-mm standard breathing tube. For plant or animal respiration experiments, the O2 consumption can be measured and if used in conjunction with the CO2 sensor, compared to the CO2 production. Analog sensor.
