The main control circuit 5 is provided with a rechargeable battery 11 , and the sealing cover 8 is provided with a tie ring 12 .

The measuring method of the marine seawater surface water temperature measuring device is characterized in that it comprises the following steps:

(1) The adjustment and setting of the measured water depth is realized by adjusting the length of the float and the water temperature measuring device;

(2) Throw out the water temperature measuring device by throwing the rod, and retract it after the measurement;

(3) Record the data sequence for a period of time;
