[0002] During the processing of pure water, it is necessary to detect its properties such as acidity and alkalinity, stability, etc. The pH value of pure water is mainly detected by a detector. When the existing water quality detection device is in use, it is necessary to fix the detection device through a fixed bracket to prevent the probe of the detection device from touching the bottom or side wall of the container, resulting in errors in the detection data. And when the device is out of use, the bottom probe is easily damaged by external impact, affecting subsequent detection and use. To solve the above problems, a water quality detection device for pure water processing is needed.
