Vernier O2 Gas Sensor


SchoolMart Part #: V-O2-BTA Brand:


Very important: Do not place the sensor into any liquid. The sensor is intended only for measuring gaseous, not aqueous, O2 concentration.

The O2 Gas Sensor measures oxygen concentration in air. The O2 Gas Sensor requires no special preparation or calibration-just plug it into your interface and it is ready to take readings.


Many of the experiments currently performed using the CO2 Gas Sensor can be performed or complemented using the O2 Gas Sensor. Due to its wide measurement range, the O2 Gas Sensor can also be used to monitor oxygen concentration during human respiration.

Included with the O2 Gas Sensor is a 250-mL bottle to be used as a respiration chamber for studying plants and insects, or rusting of iron.

For LabQuest Mini, NXT Sensor Adapter, LabQuest, SensorDAQ, EasyLink, CBL 2, Go!Link, and LabPro.
