Seawater temperature and salt calibration data acquisition device

The utility model relates to a seawater temperature and salt calibration data acquisition device, which comprises a thermostatic bath with a simulated seawater environment; wherein a support frame isarranged in the thermostatic bath, and two or more detected CTDs are fixed on the support frame; a standard temperature sensor and a standard conductivity sensor are arranged; the standard temperaturesensor and the standard conductivity sensor are connected through a watertight cable and can be lowered to the position, close to a detected CTD, in the thermostatic bath, and the standard temperature sensor, the standard conductivity sensor and the detected CTD are located at the same depth. According to the utility model, real-time measurement of the temperature and the conductivity in the thermostatic bath can be realized, standard temperature and standard conductivity values can be provided for experimenters, and abnormal conductivity conditions in the experiment process can be discovered. The conductivity standar
