Monitor gaseous oxygen levels in a variety of biology and chemistry experiments. Intended for measuring gaseous, not aqueous, O2 concentration.
The O2Gas Sensor measures oxygen concentration in air and is temperature compensated for use in many different environments. A wide measurement range allows the sensor 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.
