What are the reasons why the online residual chlorine detector cannot detect the data?

The online residual chlorine detector is an advanced online intelligent residual chlorine detection instrument. It is made of imported components and permeable membrane heads, based on polarographic analysis technology, advanced production technology and surface mount technology, ensuring the long-term operation of the instrument. Stable reliability and accuracy. But what is the reason why the online residual chlorine detector fails to detect data during use? How to maintain the electrodes of the online residual chlorine detector? Reasons why the online residual chlorine detector cannot detect data: ①Incorrect wiring ②Incorrect calibration of the instrument ③No electrolyte in the electrode; damaged or dirty diaphragm, silver metal in the electrode is oxidized ④Confirm whether there is residual chlorine in the water body and whether the flow rate reaches Requirements ⑤ When the concentration of residual chlorine or chlorine dioxide is low, the constant voltage electrode is more sensitive than the polarographic electrode ⑥ How to maintain the electrode or the electrode of the online residual chlorine detector for meter failure? 1. The electrode of the online residual chlorine detector should be cleaned regularly. When disassembling and cleaning the electrode, the oxygen permeable membrane should not be broken, and the oxygen permeable membrane on the electrode should not be wiped with filter paper, so as not to damage the oxygen permeable membrane. 2. The cable connector must be kept clean and must not be exposed to moisture or water. 3. When the displayed value is very different from the actual value, the electrolyte in the electrode may be dry, and the electrolyte needs to be refilled. Generally, the maintenance work of replacing or adding electrolyte is carried out every 6 months; when the permeable membrane is broken, it is necessary to Replace the spare one-piece membrane head. The electrode needs to be repolarized and calibrated every time the electrolyte is replaced or added or the spare integrated membrane head is replaced. 4. Electrode polarization: After the electrode is connected to the online residual chlorine detector, it is continuously powered on for more than 2 hours, which is polarization, and the calibration can only be performed after the electrode is polarized. 5. When the on-site water is cut off for a long time or the online residual chlorine detector is not used for a long time, the electrode should be taken out in time, cleaned and put on the protective cap. 6. If the electrode connected to the online residual chlorine detector fails, the electrode needs to be replaced.
