    Time:December 2, 2025


    In the daily operation of county - level water treatment plants, the online residual chlorine automatic sensor acts like a "little guardian" of water quality safety, constantly monitoring the residual chlorine content in the treated water leaving the plant. However, if this "little guardian" malfunctions, it can lead to big troubles. Next, the experts from Maideshi Residual Chlorine Water Quality Monitor Manufacturer will provide you with a detailed explanation!

     Customer Pain Point: Low Data Causes Losses

    A county - level water treatment plant encountered such a troublesome situation. The data from their online residual chlorine water quality sensor was continuously 18% lower than normal, which directly led to the non - compliance of the residual chlorine content in the treated water leaving the plant. The water quality supervision department didn't ignore this issue and immediately issued a notice for rectification. During the rectification period, the water plant had to reduce production, resulting in a loss of over 80,000 yuan. After a careful investigation, it was found that a large amount of organic matter and scale had adhered to the electrode surface, and the plant hadn't carried out maintenance according to the manufacturer's specifications.

      Revealing the Core Reasons for Inaccurate Data

    1.  Inadequate and Infrequent Cleaning 

    The manufacturer clearly requires weekly electrode cleaning, but the plant only gave it a simple wipe once a month. Over time, biofilms and scale accumulated, like a thick "cotton - padded jacket" on the electrode, preventing it from accurately sensing the residual chlorine content.

    2.  Improper Use of Cleaning Agents 

    They replaced the original factory - specific cleaning agent with an ordinary one. The ordinary cleaning agent isn't powerful enough to completely remove stubborn contaminants. It's like trying to clean a greasy pot with an ordinary brush; it just won't work.

    3. Over - used Electrodes 

    The electrodes had been in use for 28 months, far exceeding the manufacturer's recommended replacement cycle of 12 - 24 months. The diaphragm had aged and failed, making the electrode as slow - reacting as an old person, and thus unable to accurately detect the residual chlorine content.

      Professional Guidance from the Manufacturer

    1.  Regular Electrode Cleaning 

    The manufacturer recommends soaking the electrode in the original factory - specific cleaning agent (with an enzyme - based formula) for 5 minutes every week. This enzyme - based formula is like a group of hard - working little cleaners that can penetrate deep into the contaminants and break them down. Then, gently brush the surface with a soft brush to remove stubborn dirt, and finally rinse and dry it. After this process, the electrode is like having a refreshing bath and can work vigorously again.

    2.  Professional Electrode Activation 

    Soak the electrode in the original factory activation solution for 30 minutes every 3 months. The activation solution is like a "shot in the arm" for the electrode, restoring its reaction sensitivity and making it "agile" again.

    3.  Timely Electrode Replacement 

    According to the manual, the electrodes should be replaced every 18 months. The manufacturer's technicians will come to the site for installation and calibration to ensure the electrodes work accurately. It's like replacing a car's engine, rejuvenating the whole system.

      Outstanding Product Adaptability Advantages

    This online residual chlorine automatic sensor uses a highly selective permeable membrane electrode with strong anti - pollution ability. As long as it is used in conjunction with the manufacturer's maintenance plan, the measurement accuracy can be controlled within ≤±0.02mg/L. The electrodes come with a 1 - year warranty, and the manufacturer also provides free on - site maintenance training and calibration services, making it more worry - free for users.

      Extended Scenarios: Maintenance Specifications Ensure Accuracy

    The raw water in water treatment plants contains complex organic matter, and the electrodes are easily contaminated. Just as a car needs regular engine maintenance to run stably, the online residual chlorine automatic sensor can maintain its accuracy only by following the manufacturer's maintenance specifications of "regular cleaning + professional activation + timely replacement".

     Ensure Accurate Data According to the Guide

    In conclusion, by strictly following the maintenance guide of Maideshi Residual Chlorine Water Quality Sensor Manufacturer, the problems of electrode pollution and aging can be completely solved, ensuring the accuracy of the residual chlorine detection data in the treated water leaving the plant. Generally, the manufacturer's after - sales service also provides 24 - hour technical support and emergency on - site replacement services, allowing water treatment plants to use the online water quality automatic analyzer more confidently and provide safe and reliable drinking water for residents.
