The Go Direct O2 Gas Sensor measures gaseous oxygen concentration levels and air temperature. It is useful for a variety of biology and physiology experiments. It connects wirelessly via Bluetooth® wireless technology or wired via USB to your device.
Description
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 Go Direct robust rechargeable battery offers long battery life and provides always-ready operation. Monitor battery life directly from our free Graphical Analysis™ 4 app. 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.
