    Time:November 14, 2025


    In the production process of tea factories, the quality of the water used to wash fresh tea leaves directly affects the quality and taste of the tea. And the residual chlorine content is one of the crucial indicators. Once the residual chlorine exceeds the standard, the aroma of the tea will be greatly reduced, and even a pungent chlorine smell will be produced. For tea factories that focus on tea aroma, this is undoubtedly a nightmare. Next, the manufacturer of Madeshi residual chlorine water quality analyzer will explain it to you in detail!

      Customer Pain Point: Ordinary Detectors with Insufficient Precision Damage Tea

    If the residual chlorine in the water for washing fresh tea leaves exceeds the standard, the excess chlorine will penetrate into the tea leaves. The originally fresh and natural tea aroma will be destroyed, and the tea will carry a pungent chlorine smell, completely losing the charm that tea should have. However, ordinary residual chlorine detectors have the problem of insufficient precision. For low - concentration residual chlorine, especially in the case of ≤0.05mg/L, the detection error is very large.

    Once, a green tea factory suffered a lot from this. Since ordinary detectors could not accurately detect low - concentration residual chlorine, the residual chlorine in the washing water exceeded the standard, and the batch of finished tea produced had an obvious chlorine smell. These teas could not meet the market requirements at all and were finally all returned. The factory directly lost 30,000 yuan. This is not only an economic loss but also has a negative impact on the brand image.

      Must - Choose Feature: Precise Monitoring of Low - Concentration Residual Chlorine

    To solve this problem, the online automatic residual chlorine sensor came into being. This detector focuses on the monitoring of low - concentration residual chlorine, and its precision can reach ±0.01mg/L. It is like a "precise gatekeeper" installed for the washing water, always guarding the aroma of the tea.

    It can display the subtle changes in residual chlorine in real - time. Even if there is only a slight fluctuation in the residual chlorine content, it can capture it sensitively. Moreover, it can give an early warning of the trend of residual chlorine approaching the safety threshold. In this way, the staff in the tea factory can take timely measures to adjust the residual chlorine content in the washing water to ensure that it is always ≤0.05mg/L, thus protecting the original aroma of the tea.

      Scenario Verification: Improving Quality and Increasing Revenue

    A manual oolong tea factory in Zhejiang was the first to use this online residual chlorine water quality detector, and the effect was immediate. Before using it, the complaint rate of the finished tea with chlorine smell in this factory was as high as 20%. Many consumers stopped buying the factory's products because of the chlorine smell problem. However, after using this detector, the situation has changed dramatically.

    The complaint rate of the finished tea with chlorine smell has dropped from 20% to 0, which means that the quality of the tea has been greatly improved. The aroma score of the tea has also increased by 12%, and the tea aroma is more intense and pure. The consumers' satisfaction with the tea has been greatly improved, and the retention rate of repeat customers has increased by 30%. From an economic perspective, the factory has reduced the return loss by more than 50,000 yuan per year.

     The Key Choice for Stable Quality

    For tea factories that focus on aroma, the aroma of the tea is the soul of the product. And the online residual chlorine water quality detector with a precision of ±0.01mg/L is the key weapon to guard this soul. It can prevent residual chlorine from damaging the tea and stabilize the product quality.

    In today's increasingly competitive market, only by ensuring the product quality can we win the trust and favor of consumers. Welcome to consult Madeshi, a chlorine sensor Manufacturer, at any time to ensure product quality and improve economic benefits!
