Description

Technical Field

[0001] The utility model relates to the field of water quality analysis, in particular to a measuring tank used for a water quality analyzer. Background Art

[0002] Water quality analyzers mainly use ion-selective electrode measurement to achieve accurate detection. 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 reacts with the ion charge and changes the membrane potential, so that the potential between the sample and the membrane can be detected. A calibration curve is obtained by detecting a standard solution with an accurate known ion concentration, thereby detecting the ion concentration in the sample. However, when current water quality analyzers detect water quality, water samples need to flow through different electrodes in turn. After the water sample produces an ion reaction with the previous electrode, the ion combination in the water sample is affected, resulting in low detection accuracy, prone to errors, and low detection efficiency.
