CO2-BTA CO2 Gas Sensor from Vernier Software & Technology

The CO2 Gas Sensor measures gaseous carbon dioxide in two ranges-0 to 10,000 ppm and 0 to 100,000 ppm.

You can explore human respiratory changes in CO2 levels based on exercise with the high range.

The lower range offers more sensitivity and a wider interval for cellular respiration and photosynthetic metabolism studies.

With this sensor, you can easily monitor changes in CO2 levels occurring in respiration of organisms from crickets to humans! The CO2 Gas Sensor is easily calibrated using a calibration button. A chamber with probe attachment is included for running controlled experiments with small plants and animals.
