Go Direct CO2 Gas measures carbon dioxide concentration, temperature, and relative humidity. This sensor includes built-in temperature compensation and humidity protection. A 250 mL Nalgene bottle is included for running controlled experiments with small plants and animals.
Go Direct CO2 Gas is ideal for the following experiments:
- Measure the change in CO2 gas concentration during cellular respiration.
- Measure the change in CO2 gas concentration during photosynthesis.
- Study the effect of temperature on cell respiration or metabolism of organisms.
- Study how yeast metabolize different sugars.
- Investigate artificial selection by comparing respiration rates of different yeast strains.

Care and Maintenance
Go Direct CO2 Gas contains a small lithium-ion battery. The system is designed to consume very little power and not put heavy demands on the battery. Although the battery is warranted for one year, the expected battery life should be several years. Replacement batteries are available from Vernier (order code: GDX-BAT-650).
Storage and Maintenance
To store Go Direct CO2 Gas for extended periods of time, put the device in sleep mode by holding the button down for at least three seconds. The red LED will stop flashing to show that the unit is in sleep mode. Over several months, the battery will discharge but will not be damaged. After such storage, charge the device for a few hours, and the unit will be ready to use.
Exposing the sensor to temperatures below –15°C or over 45°C will damage the sensor. Additionally, temperatures over 35°C (95°F) will reduce the battery's lifespan. If possible, store the device in an area that is not exposed to temperature extremes.
Note: It is recommended that you wash the Nalgene bottle by hand. Most dishwashers will melt plastic bottles.
Important: Go Direct CO2 Gas is neither waterproof, nor is it water resistant, and should never be immersed in water.
If any liquid gets into the device, immediately power the unit down (press and hold the power button for more than three seconds). Disconnect the sensor and charging cable, and remove the battery. Allow the device to dry thoroughly before attempting to use the device again. Do not attempt to dry using an external heat source.
Note: Damage due to liquid is not covered under warranty.
