Problems solved by technology

[0003] In the existing liquid sensing and detection device, the electrode is a fixed device and cannot be replaced, and the sensitive element is directly plated on the surface of the electrode head. After a period of use, the plated sensitive element on the electrode head will be damaged or fall off. As a result, the entire electrode needs to be replaced again, which causes a certain waste of manpower and material resources; and the existing liquid sensing detection device cannot measure various substances in the liquid sample, and multiple liquid sensing detection devices that can detect different substances are required. The device measures different substances separately, and the operation process is complicated
