The Vernier CO2 Gas Sensor equips students to easily monitor changes in CO2 levels occurring in respiration of organisms ranging from peas to humans.
The sensor measures gaseous carbon dioxide levels from 0 to 100,000 ppm in two ranges:
• Low range: 0 - 10,000ppm
• High range: 0 - 100,000ppm

The lower range offers more sensitivity for cellular respiration and photosynthetic metabolism studies.
The higher range allows exploration of human respiratory changes in CO2 levels based on exercise.

A 250mL respiration chamber with probe attachment is included for running controlled experiments with small plants and animals.

• Response time: 95% of full-scale reading in 120 seconds
• Warm-up time: 90 seconds
• Pressure effect: 0.19% of reading/mm of Hg from standard pressure
• Output signal range: 0-4.0V
• Gas sampling mode: diffusion
• Normal operating temperature range: 25°C (±5°C)
• Operating humidity range: 5–95% (non-condensing)
• Storage temperature range: –40 to 65°C
• Measurement Range:
     Low range: 0 to 10,000ppm CO2
     High range: 0 to 100,000ppm CO2
• Typical Accuracy (at standard pressure, 1 atm):
     Low range:
          0 to 1,000ppm: ±100ppm
          1,000 to 10,000ppm: ±10% of reading
     High range:
          0 to 1,000ppm: ±100ppm
          1,000 to 100,000ppm: ±20% of reading
• Typical Resolution:
     0 to 10,000ppm CO2: 3ppm
     0 to 100,000ppm CO2: 30ppm

    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
    ACSBL115 - Maintaining the internal environment - Homeostasis - Animals, whether osmo-regulators or osmo-conformers, and plants, have various mechanisms to maintain water balance that involve structural features, and behavioural, physiological and homeostatic responses
    ACSBL111 - Maintaining the internal environment - Homeostasis - Changes in an organism’s metabolic activity, in addition to structural features and changes in physiological processes and behaviour, enable the organism to maintain its internal environment within tolerance limits
    ACSBL110 - Maintaining the internal environment - Homeostasis - Homeostasis involves a stimulus response model in which change in external or internal environmental conditions is detected and appropriate responses occur via negative feedback; in vertebrates, receptors and effectors are linked via a control centre by n
    ACSSU149 - Biological Sciences - Cells - Cells are the basic units of living things and have specialised structures and functions
    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
