The utility model lower end in sleeve pipe is provided with the water temperature testing element.

The utility model good effect is as follows: water temperature and water level induction line and element thereof all are encapsulated in the sleeve pipe, do not contact with water, and no little electric current flows through in the water, there are not negative electrode and anode to visit point, the absorption incrustation scale can not appear visiting or by the phenomenon of electrolytic etching, so induction is sensitive, and long service life.
