Carbon Dioxide Gas Sensor

The PASPORT Carbon Dioxide Gas Sensor remains the best available for schools. Measure the carbon dioxide from cricket respiration, pea germination and yeast respiration to human breath, even cola “fizz” and auto exhaust. Up to 300,000 ppm range. Or measure the carbon dioxide absorbed during photosynthesis—demonstrate the important role of photosynthesis in the biogeochemical cycle.
