O2 Gas Sensor

$219.00

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.

ORDER CODE: O2-BTA Categories ,
Education Levels

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.
