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. It 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 an entire weekend, making it ideal for long-term, carbon cycling investigations. The included 250-ml sample bottle supports analyses with multiple gas sensors.
