A water quality testing system includes a water quality testing device, a water-detaching airbag connected to the water quality testing device, and an inflation module. The water quality testing device includes a main body, a sensing light source, a fluorescence sensing film, a photodetector, and a signal processor. The sensing light source is disposed within the main body and emits sensing light. The fluorescence sensing film is disposed on the surface of the main body and receives the sensing light to generate feedback light. The photodetector is disposed within the main body and receives the feedback light to generate a concentration signal. The signal processor is disposed within the main body and connected to the photodetector, and determines the concentration of the analyte in the aqueous solution based on the concentration signal. The inflation module is used to inflate or deflate the water-detaching airbag. The water-detaching airbag is disposed within the main body and, when inflated, causes the fluorescence sensing film to float above the liquid surface.
