Production of online multi parameter water quality analyzer

The multi parameter water quality analyzer mainly uses ion selective electrode measurement method to achieve accurate detection. Electrodes on the instrument: pH, fluoride, sodium, potassium, calcium, magnesium, and reference electrode. Each electrode has an ion selective membrane that reacts with the corresponding ions in the sample being tested. The membrane is an ion exchanger that changes the membrane potential by reacting with the ion charge, allowing for the detection of the potential between the liquid, sample, and membrane. The difference between the two potential values detected on both sides of the membrane will generate current. The sample, reference electrode, and reference electrode liquid form a "circuit" on one side, while the membrane, internal electrode liquid, and internal electrode are on the other side. The difference in ion concentration between the internal electrode solution and the sample will generate electrochemical voltage on both sides of the membrane of the working electrode. The voltage is led to the amplifier through the highly conductive internal electrode, and the reference electrode is also led to the location of the amplifier. By detecting a precise standard solution with known ion concentration, a calibration curve can be obtained to determine the ion concentration in the sample. When the measured ions in the solution come into contact with the electrode, ion migration occurs within the aquifer of the ion selective electrode substrate. The change in charge of migrating ions results in a potential change, causing a change in the potential between the membrane surfaces and creating a potential difference between the measuring electrode and the reference electrode.
