Product Summary
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 an ideal tool for studies of photosynthesis, respiration, and oxygen cycling. With remote logging, experiments can run beyond the lab period and easily give students hours or days of data to analyze. In addition to measuring oxygen gas levels, the Wireless Oxygen Gas Sensor also contains sensors to measure ambient temperature and humidity.
Note: Store the units in a sealed bag with minimal air space to extend the life of the sensing element.
