[0002] Detection devices that facilitate the replacement of reference electrodes are of great significance in the field of electrochemical sensors and are widely used in environmental monitoring, medical diagnostics, and industrial control. These devices feature a modular design for rapid replacement, an integrated intelligent recognition system for automatic calibration, and corrosion-resistant materials for enhanced stability. These new devices hold broad application prospects in environmental, water quality, medical, and industrial monitoring, improving the convenience and accuracy of detection and advancing electrochemical sensor technology.

[0003] A search revealed an existing patent (publication number: CN216051499U) that discloses a detection device for easily replacing a reference electrode. The device comprises a mounting sleeve, a reference electrode, and a plastic protective sleeve.

A protective cap is provided at the upper end of the plastic protective sleeve, and a connecting copper sleeve is embedded in the lower half of the mounting sleeve. The upper half of the reference electrode is provided with a connecting post, which is removably fixed to the lower end of the connecting copper sleeve and located within the plastic protective sleeve. A cable is fixed to the upper end of the connecting copper sleeve, and the other end of the cable extends through the upper wall of the plastic protective sleeve. This device has the advantages of simple structure, convenient installation, ease of disassembly, and high practicality.

[0004] However, during the actual use of the above solution, the reference electrode cannot be corrected, which may lead to certain shortcomings. First, the measurement accuracy is reduced, affecting data reliability. Second, the data repeatability is poor, resulting in significant differences in measurement results at different times or under different conditions, making it difficult to establish a stable benchmark. In addition, the inability to effectively calibrate increases maintenance costs, and frequent replacement of reference electrodes may also reduce user confidence, affecting the frequency of use and promotion of the device. In application scenarios with high precision requirements, this limitation further restricts the scope of application of the device, thereby affecting the overall performance and user experience.
