Fluid resistivity measuring device

The utility model provides a fluid resistivity measuring device. The fluid resistivity measuring device comprises an accommodating structure, a voltage measuring structure and a current measuring structure, the containing structure comprises a cylinder and a base. The periphery of the base is hermetically connected with the inner wall of the bottom of the cylinder; wherein the base and the cylinder are enclosed to form a first accommodating space for accommodating measured liquid; the voltage measuring structure comprises a first universal meter, a first wire and a second wire. The first universal meter comprises a first end and a second end which are different. The first end is connected with the bottom end of the measured liquid through a first wire; the second end is connected with thetop end of the measured liquid through a second wire; a first preset distance is reserved between the end, away from the first universal meter, of the first wire and the end, away from the first universal meter, of the second
