Description

technical field [0001] The invention belongs to the field of sensing and detection, in particular to a liquid sensing and detecting device with constant temperature and replaceable electrodes and sensitive elements. technical background [0002] The liquid sensing detection device is a detection device used to detect the substances contained in the liquid sample. The reaction liquid reacts with the sensitive element on the electrode head to form a sufficient electrical signal, which is obtained by analyzing the electrical signal by the processing chip. The content of the substance to be determined in the liquid sample, such as the determination of the heavy metal content, OD dissolved oxygen content or pH value of the liquid sample, etc. [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.

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
