Wireless CO2 (Carbon Dioxide) Sensor (Local Stock)

Product Code: PS-3208-LS


Measure changes in carbon dioxide (CO2) gas levels quickly and easily with the Wireless COSensor. The sensor is temperature compensated and can operate in high humidity environments, like the included sample 250-mL sample bottle. This sensor employs live data to make core labs, such as photosynthesis, cellular respiration, and metabolism experiments engaging and impactful. With the ability to store more than 55,000 data points, this sensor enables studies to run overnight or throughout the entire weekend for carbon cycling investigations. The included 250-ml sample bottle supports analyses with multiple gas sensors. Wash metabolism chamber with warm soap and water.  DO NOT wash in boiling, dishwashers with hot cycle or autoclaves as plastic will deform.


  • Logging ability for long-term experiments, store up to 55,000 data points
  • Integrated stopper for use with sample bottle and common glassware
  • Temperature-compensated for accurate results

Perform These Experiments

  • Monitor CO2 levels during photosynthesis and respiration experiments
