[0019] 1. In the indicating electrode of this water quality analyzer, when using the indicating electrode, first insert the mounting block on the left wall of the first protective tube into the mounting groove on the right wall of the second protective tube. When the mounting block enters the mounting groove, the rubber sleeve on the outside of the mounting block will squeeze the inner wall of the mounting groove. Then, insert the electrode body at the lower end of the sealing cap into the inside of the first and second protective tubes. Next, rotate the connector so that the internal thread on the inner wall of the connector connects with the external thread on the outer wall of the first and second protective tubes, thereby installing the sealing cap on the upper end of the first and second protective tubes. Then, immerse the electrode body into the... In the test solution, a hydration layer of about 0.1 mm forms on the surface of the glass diaphragm bulb. Under acidic conditions, hydrogen ions in the test solution enter the hydration layer, and under alkaline conditions, hydrogen ions in the hydration layer diffuse into the test solution. This exchange and diffusion process of hydrogen ions creates a membrane potential, which allows for water quality analysis. The use of mounting grooves, mounting blocks, rubber sleeves, internal threads, external threads, threaded connections, and snap-fit ​​mechanisms enhances the ease of installation and disassembly of the first and second protective tubes, thereby effectively improving the efficiency of maintenance and replacement of the indicator electrode of the water quality analyzer.

Then, immerse the electrode body in the solution to be tested. The solution to be tested will pass through the filter screen inside the protective ring and come into contact with the glass diaphragm ball, so that a hydration layer of about 0.1 mm will be formed on the surface of the glass diaphragm ball. The filter screen can intercept impurities in the solution. Through the cooperation of the locking blocks, slots, inserts, slots, connecting plates, springs, insertions and locking, the stability of the protective ring installation and the convenience of disassembly are enhanced.
