Product Description
A quantitative potassium dichromate solution was added to the sample. In a strong sulfuric acid medium, silver sulfate was used as a catalyst, and mercury sulfate was added as a chlorine ion masking agent. After the mixture was sealed at a high temperature and pressure of 165° C., the hexavalent chromium was quantified. The trivalent chromium is converted to trivalent chromium, and the color of the mixed solution is changed. The color change is measured by the spectrophotometric method to calculate the actual COD value. The consumed amount of dichromate ions corresponds to the amount of oxidizable organic substances.
Features:
1. The use of HJ/T399-2007 "Determination of water quality - chemical oxygen demand - rapid digestion spectrophotometry", the industry recognized high;
2. Unique three-level precision photoelectric metering device, rapid and accurate reagent extraction, significantly reducing the impact of peristaltic pump tube aging;
3. Precise temperature compensation algorithm and ambient light elimination measures, the accuracy is always the same regardless of seasons;
4. Highly reliable reagent selection valve and digestion bottle assembly, low failure rate, low maintenance workload;
5. Intelligent diagnosis system, low consumption of reagents, convenient operation and maintenance of equipment, lower operation and maintenance costs;
6.Automatic calibration, one-click cleaning function, ensure accurate measurement of equipment and clean and pollution-free reagent channels;
7.Completely eliminate pressure detection protection, temperature protection and leakage alarm function to ensure safe operation of equipment;
8. Automatically controlled safety gate design, careful care of the safety of equipment operation and maintenance personnel;
9. Large-capacity storage space, save more than five years of measurement data and log information, a complete list of equipment operation status;
10. System remote control function and system failure, power failure, lack of reagents, missing sample automatic alarm and status upload function;
11. More user-friendly touch-type graphical interface, the operation is extremely simple, no labor memory, within reach.
