OAS insttype Detail for Shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement
|<< previous|||revision: 5|
|Term:||Shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement|
|Definition:||A carbon dioxide equilibrator is usually in the shape of a vertical tube, with a shower head on the top, some head space, 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.
