COD/Total Phosphorus/Ammonia Nitrogen Analyzer W623, 2-15000 mg/L (CAT#: STEM-AL2-0520-ZJF)

The COD/Total Phosphorus/Ammonia Nitrogen Analyzer W623 is designed for colorimetric water-quality analysis. It combines photometric measurement with source-listed digestion conditions for water samples. The instrument is configured to determine COD, total phosphorus, and ammonia nitrogen. Concentration results are read directly from the analytical measurement workflow. Batch digestion is supported for multiple sample tubes. The source provides parameter-specific digestion times for the listed analytes. Sealed or open digestion operation is supported where stated for the model. The product is intended for routine analytical use with the source-listed configuration.
