<p>A movable positioning device of the thermoscope in the aquarium is disclosed to overcome the disadvantages of the existing thermoscope fixed by a suction cup made of rubber, which is not only handled inconveniently, but also tends to cause electricity leakage. The present device comprises a carrying seat of the thermoscope located inside of the aquarium wall and a controlling element located outside of the aquarium wall and controlling movement and orientation of the bearing-seat. Magnets are disposed in the controlling element and the carrying seat respectively, and the control element and the carrying seat are fixed to both inside and outside surfaces of the aquarium wall by magnetic force. Movement and orientation of the carrying seat can be achieved by controlling that of the controlling element outside of the aquarium, so as to measure the temperature at any positions inside of the aquarium at any time.</p> |
