Wireless O2 (Oxygen) Sensor (Local Stock)

Product Code: PS-3217-LS


The Wireless Oxygen Gas Sensor measures gaseous O2 concentration 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.


  • Bluetooth® and USB connectivity
  • 0-100% Oxygen Gas Concentration
  • ±1% Oxygen at constant temperature and pressure
  • Also reports ambient temperature and humidity
  • 2-3 year operating life with replaceable sensing element

No need for an interface.

All PASCO Wireless Sensors connect to computers, Chromebooks, and tablets, through Bluetooth 4. No other equipment required! Our software (SPARKvue or PASCO Capstone) allows students to see and analyze data in real-time.

Long-lasting, rechargeable battery

The Wireless Oxygen Gas Sensor draws as little current as possible. This provides you with a long battery life for lab activities. Our software also displays the battery level at all times. If it dips too low, connect the USB cable to charge while you collect data.
