Device for continuous measuring pO2 and pCO2 of aquarium without biofouling on the sensors using air-water equilibrium

摘要

The present invention relates to an apparatus for continuously measuring oxygen and carbon dioxide in a farm environment without biological contamination of the sensor, and more particularly, to a floating member in which a head space is formed by partially submerged in seawater inhabited by micro-organisms. A bubble introduction pipe that is submerged in the seawater and communicates with a lower portion of the floating member; A dehumidifier that communicates with one side of the upper portion of the floating member to dehumidify air provided from the floating member; A first circulation pipe through which air flowing out through the dehumidifier is circulated and flows into the floating member; A second circulation pipe through which air flowing out through the dehumidifier is circulated and flows into the floating member; A carbon dioxide partial pressure measuring device for measuring a partial pressure of carbon dioxide in the air provided into the first circulation pipe; And an oxygen partial pressure measuring device for measuring a partial pressure of oxygen in the air provided into the second circulation pipe.
