The O2 Gas Sensor measures oxygen concentration in air, and is temperature compensated for use in different environments. It has a wide measurement range, allowing it to be used to study human and cellular respiration. The O2 Gas Sensor also includes a 250 mL bottle that can be used to study the rusting of iron or as a respiration chamber for monitoring plants and insects.
