[0021] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] like Figure 1 As shown, the utility model provides a titration device based on the evaluation of the scale inhibition performance of the scale inhibitor, comprising:

[0025] The dosing sub-device 1 is used to add scale inhibitors to the reaction container 2, and the reaction container 2 reacts according to the scale inhibitor. The first control valve 3 is used to control the opening and closing of the first pipeline. The first control valve can be used to set the extraction of quantitative solution. The EDTA container 7 is used to provide EDTA solution. The second control valve 6 is used to control the opening and closing of the second pipeline. The liquid level display 8 is used to display the volume data of the liquid in the EDTA container 7.

[0026] Specifically, the change in the color of the solution is determined by detecting the change in intensity and wavelength, and the color change of the solution in the titration container 4 is determined.

[0027] Specifically, the color recognition sensor recognizes the color change of the solution in the titration container. When the color change of the solution is detected, the indicator light changes, and the switch of the second control valve 6 is manually adjusted according to the change of the indicator light.

[0028] Specifically, the second control valve 6 is a manual control valve.
