WS1503 Ammonia Nitrogen Water Quality Online Automatic Monitoring Instrument
WS1503 Ammonia Nitrogen Water Quality Online Automatic Monitoring Instrument
Product details
The principle of WS1503 ammonia nitrogen water quality online automatic monitoring instrument adopts salicylic acid spectrophotometry. Under the conditions of alkaline medium and sodium nitroprusside (nitroprusside), ammonium reacts with salicylate and hypochlorite ions to generate water-soluble blue compounds. The substance has maximum absorption at 697nm. The content of ammonia nitrogen in the water sample is measured by photoelectric colorimetry according to Lambert Beer's law. Add specific masking agents to remove the interference of cations (especially calcium and magnesium ions).
1. Three level precision photoelectric measuring device, fast and accurate reagent extraction, greatly reducing the impact of peristaltic pump tube aging;
2. Accurate temperature compensation algorithm and ambient light elimination measures ensure consistent accuracy regardless of spring, summer, autumn, or winter;
3. Highly reliable reagent selection valve and digestion bottle components with low failure rate and minimal maintenance workload;
4. Low temperature condensation device, a breakthrough solution to the problem of long-term storage of reagents.
