[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] Pressing the connecting rod lowers the sealing column, releasing the seal on the inlet. Titrant and the water to be analyzed can then be poured into the inlet. The titrant and water will flow along the inner wall of the sealing column into the outlet, and then into the inlet pipe and the liquid container. Once finished, releasing the connecting rod causes the spring to pull the sealing column back up to its original position. The sealing column then re-enters the inlet, sealing the inlet pipe and preventing air from entering. Connecting to a power source via the charging interface charges the battery. The control panel allows the battery to supply power to the power line. The current in the power line flows through the test electrodes into the liquid in the container for potentiometric titration. The detection probe contacts the liquid in the container to perform detection, thus analyzing the water quality.

[0018] This invention is simple to use. The sealing column seals the water inlet hole with the elastic force of the spring, so that it can be sealed directly after the liquid is poured to prevent air from contacting the liquid in the container. The liquid level in the container can be known by observing the measuring ruler. Moreover, the base adopts a small volume design, so the handle can be lifted directly to move the entire base.
