The online residual chlorine detector is an online continuous analysis instrument, which uses LED light source for colorimetric analysis and measurement of residual (total) chlorine concentration. The typical analysis procedure of the analyzer is set inside the system, such as: flush the optical reaction cell with the sample, extract a part of the sample at the same time, add one or more reagents, such as buffer or masking agent, and then perform a second measurement as a reference measurement value. Reference measurements eliminate confounding factors such as sample color and turbidity, as well as various colors from pharmaceuticals and refracted light. Online residual chlorine detector is usually used in food and beverage, medical and health, CDC, tap water supply, secondary water supply, swimming pool, breeding and other industries. Correct maintenance in daily life is beneficial to prolong its service life. The following content will briefly introduce you: 1. After turning on the power, the instrument should display. If there is no display or the display is abnormal, turn off the power immediately and check whether the power is normal. . 2. The secondary meter generally does not need daily maintenance. When there is an obvious failure, please do not open it to repair it yourself, and contact us as soon as possible! 3. The cable connector must be kept clean, and must not be affected by moisture or water, otherwise the measurement will be inaccurate. 4. The electrode should be cleaned frequently to ensure that it is not polluted. 5. Calibrate the electrodes every once in a while. 6. When the water is cut off, make sure that the electrode is soaked in the liquid to be tested, otherwise its life will be shortened. 7. The use of the residual
chlorine analyzer depends largely on the maintenance of the electrode. At present, public places and households often use chlorine-containing disinfectants for disinfection. On the one hand, it is necessary to ensure sufficient concentration of disinfectant to ensure the disinfection effect; on the other hand, the amount of residual chlorine in the sewage discharged into the urban sewage treatment plant may be high, which will affect the normal operation of the biochemical treatment device. At the same time, excessive residual chlorine may also affect surface water, groundwater and drinking water sources, and affect the ecological environment and drinking water sources. Determining the content and state of residual chlorine in water is of great significance to the disinfection effect, environmental water quality and drinking water safety. Therefore, the existence of residual chlorine detector is of great significance to environmental protection. The desktop residual chlorine analyzer can measure residual chlorine and total chlorine in water, and has the characteristics of easy operation and high sensitivity. It is widely used in on-site rapid detection of water quality in the fields of urban water supply, food and beverage, environment, medical treatment, chemistry, pharmacy, thermoelectricity, papermaking, aquaculture, bioengineering, fermentation technology, textile printing and dyeing, petrochemical industry, water treatment, etc.
