1、 Product Usage:

The WS-05 water quality analyzer mainly measures COD in sewage_CrFive parameters: total phosphorus, ammonia nitrogen, suspended solids, and total nitrogen, COD_CrAdopting rapid digestion method, the operation process is simple, fast, and economical, and the measurement results have good comparability with traditional titration method; The total phosphorus is determined using the ammonium molybdate spectrophotometric method specified in the national standard. Potassium persulfate is used to oxidize all phosphorus in the water sample to orthophosphate, which is accurate and meets the requirements of water quality testing; Ammonia nitrogen is measured using Nessler's reagent spectrophotometry. When the tested water sample is added with the reagent, the water sample turns yellow, and the instrument reads the value of ammonia nitrogen based on the depth of the yellow color. This instrument is suitable for water quality testing in large, medium, and small sewage treatment plants, and can be widely used for sewage testing in industrial, chemical, environmental protection, and pharmaceutical industries. It is a commonly used laboratory instrument.
