Principle and application of residual chlorine analyzer Turbidity measurement: 90° light scattering principle Suspended solids measurement: transmitted light absorbance method Residual chlorine measurement: DPD method is used for turbidity/suspended solids concentration/residue Chlorine measurement. Chlorine Meter Features: LCD Chinese display, good man-machine dialogue interface, easy to operate. Small in size and light in weight, it is suitable for both laboratory and field use. Automatic range conversion, high sensitivity, wide measurement range. A variety of turbidity units can be switched freely to meet various needs. According to the needs of users, the function of adding suspended solids measurement can be added. Precautions for operation of residual chlorine analyzer: 1. Chloride ion is not the measurement category of residual chlorine. Chlorine measurement includes the measurement of free chlorine and combined chlorine content. 2. For the determination of free chlorine, the pH must be 6.2---6.5, and the DPD reagent should be added for direct reaction to generate a red compound. If the pH value is out of range, please adjust it with buffer reagent or dilute acid or dilute alkali. 3. The principle of the method for measuring total chlorine: when the pH is 6.2----6.5, add excess potassium iodide, add DPD to react directly, and generate a red compound. If the pH value is out of range, please adjust it with buffer reagent or dilute acid or dilute alkali. 4. The turbid sample must be filtered before measurement. 5. It cannot be measured for colored samples. 6. The cuvette should be cleaned and stored dry after each use. How to use the residual chlorine detector: 1. Turn on the machine and preheat the machine for 2 minutes. 2. Pour the liquid to be tested into the cuvette 1, and fill it up to two-thirds of its volume. The process of putting in requires water stains not to reach the outside of the cuvette. Put this cuvette 1 into the measuring pool; press the calibration key to make the instrument display 0.00mg/L. 3. Take 100ML of the solution to be tested, add 15ML of the buffer reagent, add 5ML of the DPD reagent, and press the confirmation key; at this time, the screen display of the instrument decreases from 60 to 0; at this time, pour the solution to be tested with the reagent into the ratio Color cell 2; put the color cell 2 into the measuring pool, and the displayed degree is the residual chlorine content. 4. Press the storage key and the extraction key to store and extract 20 experimental records respectively. Features of the residual chlorine tester: 1. Microcomputer, LCD backlit liquid crystal display, light touch keyboard, easy to use. 2. Microcomputer data processing, the instrument has built-in 5-point calibration, and users can calibrate 10 more points by themselves. 3. One-key restore factory settings, maintenance-free. 4. USB interface, which can store 300 new measurement data, and connect to PC to store/print test results. 5. Concentration direct reading digital display, historical record query, real-time clock display. 6. The unique positioning structure and high-precision optical path system effectively ensure the accuracy and repeatability of the measured values. 7. Its reliable linear compensation system makes the measurement data more accurate and more stable. 8. Using high-quality imported integrated circuits and photoelectric detection components, it has high stability of the whole machine. 9. The performance of the instrument is stable, the resolution is high, and the resolution of the instrument reaches 0.001mg/L. 10. Desktop and portable.
