The residual chlorine analyzer is composed of two parts, a sensor and a display, which can measure the permanganate index, pH value and temperature separately, and is widely used in the continuous monitoring of permanganate index and pH value of various water bodies in the fields of electric power and water supply companies. The principle of the residual chlorine analyzer is to use the lithium battery electrolyte and the permeable membrane to separate the electrolytic cell from the water sample, and the permeable membrane has the characteristics of selectively making the clo permeable; There is a fixed potential difference between the two electrodes, and the resulting current is converted to a permanganate index concentration.
Attention should be paid to the use of residual chlorine analyzers:
1.Clean the electrodes regularly to ensure that there is no contamination. The electrodes need to be calibrated at regular intervals. Keep the electrode immersed in the test solution during the water outage to prolong the service life.
2.The quadratic meter generally does not need daily maintenance, if there is a failure, please do not repair it yourself, after starting the power supply, the instrument should be displayed. If there is no display or abnormal display, turn off the power immediately and check whether the power supply is normal.
3.Keep the cable connector clean and protected from moisture or water ingress that may affect the measurement accuracy.
Key points for the maintenance of the residual chlorine analyzer include:
1.Quadratic meters usually do not require routine maintenance, in case of obvious failure, please contact the manufacturer as soon as possible.
2.After starting the power supply, the instrument should have a display, if there is no display or the display is abnormal, the power should be cut off immediately to check whether the power supply is normal.
3.Keep the cable connector clean and protected from moisture or water ingress to ensure measurement accuracy.
4.Clean the electrodes regularly to ensure that they are not contaminated.
5.Calibrate the electrodes at regular intervals.
6.Keep the electrode immersed in the test solution during the water outage to prolong the service life.
7.The effectiveness of the residual chlorine analyzer depends largely on the maintenance of the electrode.
