Introduction: The daily analysis results of the permanganate index are closely related to the acidity of the solution, the concentration of permanganate, and the heating temperature and time of boiling water. At present, domestic laboratory analysis is mostly done by hand, with many process disturbances, large differences in conditions, low analysis efficiency, and large data errors such as parallelism and quality control. The automatic permanganate index analyzer fully complies with the classic method of the national standard permanganate index. It is equipped with independent units such as reagent liquid volume safety warning, multi-channel boiling water bath heating, constant temperature titration colorimetry, and sample robotic arm transfer to ensure high experimental efficiency. , the process interference is less, and the data is more accurate. It is suitable for automatic determination and analysis of permanganate index items in surface water, groundwater, drinking water and environmental water in various industries. Implementation standard: GB/T11892 Determination of Permanganate Index of Water Quality GB/T5750.7 Drinking Water Standard-Comprehensive Index of Organic Matter Features: 1. Comply with the national standard method, the detection process is completely consistent with the traditional manual method, the automatic "digestion-analysis" integration, all kinds of acidic and alkaline samples are automatically analyzed without personnel on duty, and the analysis results are directly output 2. The fully automatic high-speed and stable three-axis robot motion system can quickly and stably realize the transfer of the sample between the test area, the water bath area and the titration area. The high-sensitivity limit switch prevents the test failure or instrument damage caused by the operation exceeding the limit. 3. Using three-dimensional intelligent robotic arm technology, it can automatically judge whether the sample is successfully grasped, and prevent accidents during the measurement process. It is resistant to corrosion and high temperature, and can grasp the cup at high temperature. 4. The pull-out sample tray has multiple sample positions, the volume of the sample cup is ≥ 200mL, and it meets the requirements of the national standard and can fully accommodate 100mL of water samples and reagents 5. Multiple independent channels are used for digestion. Micro-boiling water bath technology is used to effectively prevent water vapor from escaping. Accurate constant temperature is achieved through PWM technology. High and low water level sensors are provided to automatically replenish water to prevent dry burning from damaging the equipment. 6. Automatic stirring and automatic titration in a constant temperature state, using bionic technology, imported color sensor simulates the human eye to identify the color judgment end point, and is not affected by sample color, turbidity impurities, etc. 7. Automatic variable-speed titration, the titration speed is intelligently adjusted according to the sample conditions, and the detection time is reasonably shortened. It has the functions of titration delay and repeated judgment, and eliminates false end points. 8. All reagents are added automatically by an independent syringe pump mechanism, accurate without calibration, without cross-contamination, avoiding direct contact between operators and strong oxidants such as sulfuric acid, potassium permanganate, and high-temperature media 9. Using a high-precision syringe pump for titration and sample addition, the titration and sample addition accuracy reaches 5‰, reducing the influence of experimental titration errors on the results 10. Equipped with a 10-inch color touch screen, built-in professional industrial control system, human-machine interactive operation, higher stability, and can carry out sample work without online connection, eliminating the unstable factors caused by wired or wireless connection 11. The built-in micro-printer can be flexibly set to automatically save and print the experimental result data, which is convenient for the experimental personnel to make statistics 12. With the function of automatic cleaning of pipelines, imported pipes are selected, which are resistant to strong acid and alkali corrosion
