Go Direct® O2 Gas Sensor product image

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.

Wired or Wireless—The Flexibility to Choose

Our Go Direct sensors connect directly to your mobile device, Chromebook, or computer using our free Graphical Analysis 4 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 solution best for your classroom or laboratory.
