The O2 Gas Sensor can be used to monitor gaseous oxygen levels in a variety of biology and chemistry experiments. The sensor is intended for measuring gaseous, not aqueous, O2 concentration.
Description
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.
