Introduction: 201W Permanganate Index Analyzer is a fully automatic integrated robot system developed by our company based on international standards GB 11892 and GB/T 5750. It is used for automatic determination and quantification of permanganate index of surface water, groundwater and other samples. analyze. Working principle: Digestion: The sample is heated and digested by potassium permanganate and sulfuric acid solution for 30 minutes; Titration: After the digestion, the excess sodium oxalate is dripped back with potassium permanganate in a constant temperature environment of 80 °C (can be set); according to the color change Judging the end point of titration; the above-mentioned "digestion-titration" process is all completed automatically by the instrument, integrated operation. Features: 1. The mechanical gripper has a position buffer function, which is compatible with sample cups of different calibers to prevent the cups from falling; 2. Water source low warning and automatic water replenishment; 3. Dedicated sample cup water removal module; 4. There are three independent groups of reagent addition level, water removal level, and drop position (drop position provides 60°-80° thermal insulation environment), and the test process is smoother; 5. Simulate human eye recognition, automatically determine the end point through color changes, and automatically deduct the excess part; 6. Can measure turbid water samples; 7. Automatically digest water samples, automatically analyze CODMn value, and realize the integration of "digestion-analysis". From sample digestion to issuing final results, the instrument is fully automatic without manual intervention; 8. Real-time display of the remaining amount of reagents, reminding to add reagents; 9. Movable sample column, samples can be added cyclically; 10. The syringe pump and dosing pump can be cleaned automatically; 11. The digestion time can be adjusted according to the needs. technical parameter: Instrument parameters: Equipped with a 32-well sample tray and 7 digestion positions; The sampling volume for a single measurement is 100mL, and the water bath heating method is used, and pure water can be added to the water bath; Test speed: less than 6 minutes.
