Description
With this sensor, you can easily monitor changes in CO2 levels occurring in respiration of organisms ranging from peas to humans. A 250 mL respiration chamber with probe attachment is included for running controlled experiments with small plants and animals.
- On the high range, you can explore human respiratory changes in CO2 levels based on exercise.
- The lower range offers more sensitivity for cellular respiration and photosynthetic metabolism studies.
