The main component of a carbon dioxide analyzer is a nondispersive infrared (NDIR) spectroscopic sensors to detect CO2 in a gaseous environment by its characteristic absorption. Carbon dioxide (CO2) gas analyzer works together with carbon dioxide (CO2) equilibrator (insttypes_id 184) to measure carbon dioxide in the water. To measure water carbon dioxide, water needs to be continuously supplied to a showerhead inside an equilibrator. As the water flows through the equilibrator chamber, dissolved carbon dioxide exchanges quickly with air in the headspace. This air is then sampled by the carbon dioxide analyzer to determine the mole fraction of CO2 in water. showerhead equilibrator showerhead equilibrator extracts dissolved CO2 from water A carbon dioxide equilibrator is usually in the shape of a vertical tube, with a showerhead on the top, some headspace, a lot of beads to increase the surface exchange area between water and air, a water seal device at the bottom to allow water to overflow, but prevents air exchange between inside and outside. Carbon dioxide (CO2) equilibrator works together with carbon dioxide (CO2) gas analyzer (insttypes_id 183) to measure carbon dioxide in the water. To measure water carbon dioxide, water needs to be continuously supplied to a showerhead inside an equilibrator. As the water flows through the equilibrator chamber, dissolved carbon dioxide exchanges quickly with air in the headspace. This air is then sampled by the carbon dioxide analyzer to determine the mole fraction of CO2 in water.
