eosGP CO2 sensor

measure soil or water CO2 concentration


The Eosense GP Sensor (eosGP) is a compact, waterproof CO2 concentration probe for continuous, accurate, in situ monitoring in harsh environments, and can withstand anything from searing summers to freezing winters.

The Eosense GP Sensor can also be installed in air as well as water columns to depths of 3m. The sensor is ideally suited for a range of applications from scientific research, aquaculture, climate change studies, carbon budgets, fertility experiments, and chemical and biological processes.


  • two available calibration options (0 to 30,000 ppm or 0 to 200,000 ppm)
  • Waterproof to 3 m
  • Low power consumption (< 1 W)
  • Quick equilibrium (< 90 s in air)
  • Logging and visualization software


who uses the eosGP?

The eosGP is currently being used by researchers, students, environmental consultants, aquaculture managers, and in water quality assessments.

Currently, the eosGP is installed in many experiments across the globe that include researchers from The University of California, Berkeley, USA, University of Hamburg, Germany, and the International Tundra Experiments, Norway.


measure CO2 in soil or water

The eosGP CO2 Sensor can be deployed in either soil or water for long-term, continuous monitoring.

The CO2 sensor is encased in a robust and rugged environmental proof enclosure that will keep the sensor safe in the harshest field conditions for years.

The eosGP CO2 Sensor is ideal for scientific research, or in industry, such as aquaculture, for continuous monitoring of atmospheric or dissolved CO2. The eosGP is rated to depths of 3m which is suitable for most aquaculture applications.
