    Time:July 23, 2025

      Summer has arrived, and various enterprises are busy with disinfection work. However, it's easy to "fail" in this task without proper attention. Many enterprises think they've done a perfect job in disinfection, but in fact, the "invisible killer" - residual chlorine - has been holding them back. Let's have a detailed explanation from the chlorine sensor Manufacturer, Meidashi Residual Chlorine Water Quality Sensor Factory.

      There are many "invisible pitfalls" in summer disinfection. As the water temperature rises in summer, the reproduction speed of bacteria is three times faster than usual, and the disinfectant water evaporates more quickly. This leads to the residual chlorine concentration fluctuating unpredictably, making it difficult to control. For example, a swimming pool suffered from insufficient residual chlorine, which caused many tourists to have skin allergies, and the pool had to pay a compensation of 100,000 yuan. Another food factory had excessive residual chlorine in the workshop after disinfection, and the produced products were found to have an unpleasant odor. Traditional detection methods also have significant problems. Manual detection is only carried out twice a day, which can't keep up with the rapid changes in residual chlorine. By the time the problem is detected, the bacteria may have already exceeded the standard severely, resulting in irreparable losses.

      The online residual chlorine detector is like having "clairvoyant eyes", which can expose three disinfection truths.

      1. "The disinfectant water is added in vain"

      In the summer afternoons, the residual chlorine often drops suddenly, indicating that the dosage of disinfectant water fails to keep up with the rising water temperature. A water plant discovered this problem through the online detector. After adjusting the dosing frequency, the disinfection qualification rate increased directly from 70% to 100%.

      2. "Adding too much causes more trouble"

      A beverage factory had excessive residual chlorine during pipeline disinfection. As a result, the produced beverages tasted astringent and had to be re - processed, causing a loss of 50,000 yuan.

      3. "The dead corners are not disinfected"

      An environmental protection sewage treatment station found through online monitoring that the residual chlorine in the corner was zero because the pipeline was blocked. After timely dredging, the risk of cross - infection was avoided.

      The online residual chlorine detector is far superior to manual detection. In terms of reaction speed, manual detection lags behind by 2 hours, while the online detector updates data every 30 seconds. Once the residual chlorine exceeds the standard, it will alarm within 1 minute. In terms of cost, the price of an online residual chlorine detector is equivalent to the annual salary of two testers, but it can avoid losses of hundreds of thousands of yuan from a single accident. It also performs excellently in terms of stability. After a hotel used the online residual chlorine detector, the fluctuation range of residual chlorine in the swimming pool was narrowed from ±0.5mg/L to ±0.1mg/L.

      How should different industries use the online residual chlorine detector?

      For swimming pools and water parks, it is necessary to focus on the linkage between real - time residual chlorine and water temperature, and automatically adjust the dosage of disinfectant water through the online residual chlorine detector. The food processing industry needs to monitor the residual chlorine content in the workshop disinfectant water and pipeline flushing water to ensure that the residual chlorine is within the safe range of 0.5 - 1mg/L. In the field of medical wastewater treatment, the residual chlorine data needs to be retained for 6 months. The online residual chlorine detector can automatically generate compliant reports, which is convenient and worry - free.

      In summer, when disinfection becomes more difficult, the online residual chlorine detector is like a reliable assistant for enterprises. It can help enterprises accurately understand the residual chlorine situation and avoid "failing" in disinfection. If you also want to make your disinfection work more efficient and reliable, welcome to consult Meidashi Residual Chlorine Water Quality Sensor Factory at any time.

      In conclusion, the Digital residual chlorine sensor and online residual chlorine detector provided by the chlorine sensor Manufacturer are essential tools for enterprises to ensure effective disinfection in summer. They offer accurate monitoring, rapid response, and cost - effective solutions to prevent potential losses caused by improper disinfection.
