Measure changes in carbon dioxide (CO2) gas levels quickly and easily with the Wireless CO2 Sensor. The sensor is temperature compensated and can operate in high humidity environments. This sensor employs live data to make core labs, such as photosynthesis, cellular respiration, and metabolism experiments engaging and memorable impact. With the ability to store more than 55,000 data points, this sensor enables studies to run overnight or throughout entire weekend studies for carbon cycling investigations. Included 250-ml sample bottle enables multiple gas sensor analysis.
- Logging ability for long-term experiments, store up to 55,000 data points
- Integrated stopper for use with included sample bottle and common glassware
- Temperature compensated for accurate results
