The utility model relates to an ocean acidification and oxygen analog device, comprises an air source, air drying filtering pressure reducer, a standby safety electromagnetic valve, CO2 Filter, drying filter, mass flow controller, the data acquisition controller, water quality sensor, exhaust valve group. Through the pH and dissolved oxygen sensor real-time monitoring sea water pH and the atomizer, the PID control mode [...], and controlling the air, N2 , CO2 In the aeration of the proportion, in order to regulate the pH of sea water and the dissolved oxygen level to the set value and to maintain the steady state. The utility model can be real-time monitoring and adjusting gas source proportion, synchronous control pH and dissolved oxygen content of the sea water, having a steady state high precision, good dynamic response, and short adjustment time and the like, and in the condition of the marine biological respiratory interference can be maintained at higher precision.
