School Savers - Vernier GDX-O2 Go Direct O2 Gas Sensor

Vernier GDX-O2 Go Direct O2 Gas Sensor

The Go Direct O2 Gas Sensor measures gaseous oxygen concentration and air temperature. This sensor has a wide measurement range, which is ideal for studying human and cellular respiration. A 250 mL Nalgene bottle is included for running controlled experiments with small plants and animals.

The Go Direct O2 Gas Sensor can be used in a variety of experiments:
•Test catalase activity under various conditions.
•Measure oxygen consumption at rest and after exercise.
•Measure the change in gas produced during photosynthesis.
•Compare the rates of cell respiration in germinating and non-germinating peas.

Rechargeable Battery—Ready When You Are
The robust rechargeable battery offers long battery life and provides always-ready operation when using the sensor wirelessly. Monitor battery life directly from our award-winning Vernier Graphical Analysis® app, as well as LabQuest® 3. Should the battery run low, simply connect the sensor to the charging cable and keep on collecting—no interruptions or inconvenience to you or your students.

Wireless or Wired—The Flexibility to Choose
Our Go Direct sensors connect directly to your mobile device, Chromebook™, or computer using our Vernier Graphical Analysis® app—no additional equipment or software purchases are necessary. Go Direct sensors can be used wired via USB or wirelessly via Bluetooth® wireless technology, allowing you to choose the best solution for your classroom or laboratory.
