The Vernier Go Direct CO2 Gas Sensor measures gaseous carbon dioxide concentration levels, air temperature and relative humidity. It can be used in a variety of biology experiments. It connects wirelessly via Bluetooth® wireless technology or wired via USB to your device.

Monitor changes in carbon dioxide, temperature and relative humidity easily with the Vernier Go Direct CO2 Gas Sensor which includes built-in temperature compensation and humidity protection. A 250 mL Nalgene bottle is included for running controlled experiments with small plants and animals.

Vernier's Go Direct CO2 Gas Sensor is ideal for the following experiments:
• Measure the change in gas concentration during cellular respiration.
• Measure the change in gas concentration during photosynthesis.
• Study the effect of temperature on cell respiration or metabolism of organisms.
• Investigate artificial selection in yeast by comparing respiration rates of different strains.

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
Vernier's Go Direct™ sensors connect directly to your mobile device, Chromebook or computer using Vernier's free Graphical Analysis™ app. No additional equipment or software purchases are necessary. Vernier Go Direct sensors can be used wired via USB or wirelessly via Bluetooth allowing you to choose the solution best for your classroom or laboratory.

GAPRO Vernier Graphical Analysis™ Pro includes all the features of the free Vernier Graphical Analysis app, plus enhanced functions for more advanced analysis. Its illustrative experiment videos and interactive graphing capabilities inspire students to explore crucial scientific concepts and analyze data in new complex and insightful ways.
GAPRO is compatible with most Vernier sensors and multiple operating systems and devices.

Vernier and Kidwind products are designed for educational use. They are not appropriate for industrial, medical or commercial applications. Details

  • Warranty: 5 year limited warranty (1 year on battery)
    • Package size (HxWxD): 108 x 108 x 216mm
    • Packed weight: 290g 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
      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
      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
      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
