VERNIER GO DIRECT O2 GAS SENSOR
The Vernier 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.

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.

Use the Vernier Go Direct O2 Gas Sensor 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 Vernier Go Direct™ robust rechargeable battery offers long battery life and provides always-ready operation. Monitor battery life directly from Vernier's free Graphical Analysis™ 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

    This product is used in teaching these Australian Curriculum codes:
    ACSSU189 - Earth and Space Sciences - Global Systems - Global systems, including the carbon cycle, rely on interactions involving the biosphere, lithosphere, hydrosphere and atmosphere
    ACSBL019 - Biodiversity and the interconnectedness of life - Describing biodiversity - Ecosystems are diverse, composed of varied habitats and can be described in terms of their component species, species interactions and the abiotic factors that make up the environment
    ACSBL021 - Biodiversity and the interconnectedness of life - Describing biodiversity - In addition to biotic factors, abiotic factors including climate and substrate can be used to and classify environments
    ACSBL053 - Biodiversity and the interconnectedness of life - Ecosystem dynamics - Cellular respiration is a biochemical process that occurs in different locations in the cytosol and mitochondria and metabolises organic compounds, aerobically or anaerobically, to release useable energy in the form of ATP; the overall process can be repr
    ACSBL029 - Biodiversity and the interconnectedness of life - Ecosystem dynamics - Models of ecosystem interactions (for example, food webs, successional models) can be used to predict the impact of change and are based on interpretation of and extrapolation from sample data (for example, data derived from ecosystem surveying techniques
    ACSBL052 - Biodiversity and the interconnectedness of life - Ecosystem dynamics - Photosynthesis is a biochemical process that in plant cells occurs in the chloroplast and that uses light energy to organic compounds; the overall process can be represented as a balanced chemical equation
    ACSSU150 - Biological Sciences - Organ Systems - Multi-cellular organisms contain systems of organs that carry out specialised functions that enable them to survive and reproduce
    ACSSU176 - Biological Sciences - Ecology - Ecosystems consist of communities of interdependent organisms and abiotic components of the environment; matter and energy flow through these systems
    ACSSU175 - Biological Sciences - Organ Systems - Multi-cellular organisms rely on coordinated and interdependent internal systems to respond to changes to their environment
