The residual chlorine detector
uses the DPD colorimetric method to detect the concentration of chlorine. Due to the addition of buffer reagents, the sample is adjusted to a certain pH range, DPD will react with residual chlorine or total chlorine in the water sample to form a purple compound, and the residual chlorine detector uses spectrophotometry to measure the change in absorbance to obtain the water sample Medium residual chlorine concentration. The residual chlorine detector can be widely used in the detection of hypochlorous acid and residual chlorine concentration in the water disinfection process of food and beverage, medical and sanitation, CDC, tap water supply, secondary water supply, swimming pool, aquaculture and other industries, so as to control the residual chlorine in the water to reach the specified level water quality standards. Residual chlorine refers to the effective chlorine remaining in the water after the water has been chlorinated and disinfected for a certain period of time. Chlorine is added to water, and after a certain period of contact, the general term for free chlorine and combined chlorine remaining in water. It means that after chlorine is put into water, in addition to consuming a part of the chlorine with bacteria, microorganisms, organic substances, inorganic substances, etc. in the water, there is still a part of the chlorine left, which is called residual chlorine. Residual chlorine can be divided into combined residual chlorine, also called combined residual chlorine; free residual chlorine refers to OC1, HOCl, Cl2, etc. in water, which have fast sterilization speed and strong bactericidal power, but disappear quickly, and are also called free residual chlorine; The total residual chlorine is the sum of combined residual chlorine and free residual chlorine. Features of residual chlorine detector: 1. The residual chlorine detector adopts DPD colorimetric method, which can detect residual chlorine. 2. The residual chlorine analyzer uses the built-in curve calibration to make the measurement more accurate. 3. The residual chlorine detector can be connected with the automatic chlorine addition pump to realize automatic chlorine addition. 4. The residual chlorine detector realizes automatic operation and analysis, and the analysis period is 2.5 minutes/10 minutes. 5. It has automatic turbidity, chromaticity compensation and automatic diagnosis functions to reduce measurement errors. 6. A set of reagents can be used for the residual chlorine tester to run automatically for 30 days, and can be used for unattended monitoring stations. Precautions and maintenance of the residual chlorine detector: 1. The electrode should be cleaned frequently to ensure that it is not polluted. 2. The voltage should be calibrated every once in a while. 3. The secondary meter generally does not need daily maintenance. When there is an obvious fault, please do not open it to repair it yourself, and contact the manufacturer as soon as possible. 4. After turning on the power, the instrument should have a display. , Check whether the power supply is normal. 5. Bi must keep the cable connector clean, and keep it away from moisture or water, otherwise the measurement will be inaccurate. 6. During the water cut-off period, ensure that the electrode is soaked in the liquid to be tested, otherwise its life will be shortened. 7. The use of the residual chlorine detector depends largely on the maintenance of the electrode.
