The Wireless Oxygen Gas Sensor measures gaseous O2 concentrations as well as humidity and air temperature for a range of biology, environmental science, and physiology activities.
The Wireless Oxygen Gas Sensor is accurate and easy to use, making it the perfect sensor for studying photosynthesis, respiration, and oxygen cycling in a closed or open system. With remote logging, experiments can go beyond the lab period and easily give students hours or days of data for analysis. In addition to measuring oxygen gas levels, the Wireless Oxygen Gas Sensor also contains sensors to measure ambient temperature and humidity.

Students use an oxygen gas sensor to investigate the catalyzed decomposition of hydrogen peroxide by catalase.
Students use an oxygen sensor to compare the rate of hydrogen peroxide decomposition with and without a catalyst.
In this lab, students will use an oxygen sensor, carbon dioxide sensor, and a temperature sensor to monitor a closed system (terrarium). After conducting their first study, students will be tasked with designing additional investigations...
In this lab, students use a variety of sensors to explore the use of terrariums as a closed system for environmental studies and design methods for exploring the interrelationships of biotic and abiotic variables within ecosystems.
In this lab, students will design and study three, small ecosystems. Students will manipulate system interactions while monitoring gas exchange, environmental conditions, and subject health.
