Product Summary
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, 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 entire weekends for carbon cycling investigations.
