Introduction: It is suitable for the determination of drinking water, source water and surface water. The measurement range is 0.05-5.0mg/L. For water with heavy pollution, less water samples can be taken and measured after proper dilution. This instrument is uniquely equipped with 28 high-intelligence automatic sampling trays. The sample does not need to be weighed. Automatic quantification-automatic addition of reagents-automatic water bath digestion-automatic titration-automatic end point recognition-automatic calculation results-data printing, automatic uploading and other functions. The whole process only needs to manually put the sample into the sample tray, and other tasks are automatically completed by the instrument, and the test results can be uploaded with one click. Your work is simpler and easier. According to the standard: GB11892-89 "Water Quality Determination of Permanganate Index" GB/T5750.7 "Comprehensive Index of Organic Matter in Drinking Water Standard" ISO8467-1986 "Water Quality Determination of Permanganate Index" Features: 1. With 28-position automatic sampling tray, the sample to be tested does not need to be weighed, and the device automatically transfers the sample to the sample area quantitatively. The sampler has a pipeline cleaning function and will not cause cross contamination. 2. High-concentration samples can be automatically diluted, and all the work can be completed only by selecting the dilution ratio. 3. Fully automatic three-axis robot motion system, quickly realize the transfer of the sample to be tested from the test area to the digestion area and the titration area; 4. The sample automatically adds sulfuric acid and potassium permanganate solution in the reagent addition area. If the sample has been acid added, click "Cancel acid addition" in the system operation area; 5. Automatic water bath digestion. After the digestion, the excess sodium oxalate is dripped back with potassium permanganate in a constant temperature environment (60-80 degrees); 6. The titration end point is automatically determined, using advanced visual sensing technology higher than the human eye, and the titration end point is automatically determined through color changes, with higher accuracy and faster reaction speed; 7. The instrument adopts a PLC control system, which makes the instrument more stable; the system automatically completes the entire experimental process and automatically outputs the experimental result data, which is convenient for the statistics of the experimenter; 8. According to the national standard, the boiling water bath heating method is adopted to make the sample heated more evenly. At the same time, it has the function of automatic water replenishment in water shortage, ensuring that the sample to be tested is completely immersed in the boiling water bath. 9. The high-precision syringe pump is used for titration and sample addition, and the accuracy of titration and sample addition reaches 3‰, which reduces the influence of experimental titration errors on the results. 10. Automatically realize the safety monitoring of the reagent liquid volume and display the reagent liquid level in real time.
