[0002] A disinfectant analyzer is a device used in on-line water quality detection to detect the residual components of disinfectants. Since various impurities are often carried in water, after using a water quality analysis instrument for a period of time, it is necessary to disinfect and clean it with a disinfectant; in order to verify that thorough rinsing has been carried out after disinfection and does not affect the subsequent water quality analysis results, it is necessary to analyze the available chlorine / residual chlorine to ensure that the available chlorine / residual chlorine is lower than the set value.

[0003] In practice, the detection and analysis of disinfectants are often not taken seriously, and there are very few manufacturers producing disinfectant analyzers; occasionally, a manufacturer produces only a simple handheld portable analyzer, and the form is superficial. In the currently available literature, there are also few records on the theme of "disinfectant analyzer".

[0004] Therefore, there is an urgent need in this field for a professional disinfectant analyzer, as an auxiliary device for water quality analysis equipment, to detect the residual disinfectant after the instrument is regularly disinfected and cleaned, so as to ensure the accuracy of the water quality analysis results.

[0037] Please refer to Figure 2 as shown in the figure, which is a structural schematic diagram of the constant pressure pool assembly in the present utility model; the constant pressure pool assembly 100 includes: a constant pressure pool 101, a constant pressure pool water inlet 102, a constant pressure pool overflow port 103 and a constant pressure pool water outlet 104. The constant pressure pool water inlet 102, the constant pressure pool overflow port 103 and the constant pressure pool water outlet 104 are respectively communicated with the constant pressure pool 101.

[0040] Preferably, the sensor assembly 200 further includes a pH electrode and / or a temperature electrode for compensating the pH value and / or temperature of the water sample to be measured to ensure the accuracy of the test to the greatest extent.

[0044] The circuit board assembly 400 is electrically connected to the display screen assembly 500 and provides electrical support for the display screen assembly 500.

[0045] Please refer to Figure 4 as shown, which is a schematic structural diagram of the display screen assembly in the present utility model; the display screen assembly 500 includes: a display screen 501, an inlaid mounting frame 502, a door panel 503, a pressing plate 504, and a sealing strip 505.
