This invention discloses a continuous conductivity measurement method and system for a hydrophobic recovery sampling branch under cooling conditions, relating to the field of conductivity measurement. It collects sample water temperature, conductivity electrode internal temperature, and flow rate data during the hydrophobic recovery sampling branch cooling process, establishing a dynamic time series reflecting thermal response lag.
