Monitor changes in carbon dioxide, temperature, and relative humidity easily with the Go Direct CO₂ Gas Sensor. 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.

The 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.
