CO2-pro atmosphere

Dissolved CO2 SensorThe Pro-Oceanus CO2-Pro Atmosphere is an advanced measurement instrument enabling scientific researchers to simultaneously measure dissolved and atmospheric carbon dioxide.

The CO2-Pro Atmosphere is ideal for scientific studies on greenhouse gases, climate change, ocean acidification, biogeochemical and oceanographic processes.

CO2 Atmospheric SensorThe CO2-Pro Atmosphere consists of 1) a NEMA box for air intake that contains separators and filters to block bulk water and aerosols; and 2) a modified version of our CO2-Pro instrument alternating between measuring pCO2 in the water and air. The air intake box is mounted in clean air, e.g., the top of a buoy or on a ship’s forward mast (for underway measurements).

The modified CO2-Pro sensor is mounted beneath a buoy, or when used in underway mode, occupies a very small space on shipboard and requires only a source of power and surface seawater. The air intake box supplies the CO2-Pro sensor with sample air through low permeability, UV-resistant tubing.

The CO2-Pro Atmosphere has the same capabilities and measurement accuracy and precision as the CO2-Pro sensor and allows users to determine CO2 fluxes in and out of the oceans.
