Vernier CO2 Gas Sensor CO2-BTA measures gaseous carbon dioxide levels by monitoring
the amount of infrared radiation absorbed by carbon dioxide molecules. Very important: Do not place the sensor directly into any liquid. IT is intended only for measuring gaseous, not aqueous, CO2 concentration.
The sensor has two settings: low range (0–10,000 ppm) and high range (0–100,000 ppm). Students can use the CO2 Gas Sensor to measure the change in carbon dioxide levels for a variety of systems, including:
A chamber containing small living things such as crickets, worms, or germinating seeds.
A terrarium of plants undergoing respiration and photosynthesis cycles.
A classroom.
A classroom.
An enclosed atmosphere containing sodium hydroxide or potassium hydroxide as CO2 scavengers.
The chemical reaction between hydrochloric acid and sodium bicarbonate.
Carbon dioxide gas diffusing through a gas diffusion tube.
Fermentation or respiration of sugars.
Human respiration under various conditions (at rest vs. after exercise).
