Vernier GDX-CO2 Go Direct CO2 Gas Sensor Description

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.

Rechargeable Battery—Ready When You Are
The robust rechargeable battery offers long battery life and provides always-ready operation when using the sensor wirelessly. Monitor battery life directly from our award-winning Vernier Graphical Analysis® app, as well as LabQuest® 3.
