Multi-parameter Water Quality Analyzer

I. Product Overview

The Smart Multi-Parameter Water Quality Analyzer is developed in accordance with the Chinese national environmental standards HJ/T 399-2007 "Water Quality - Determination of Chemical Oxygen Demand - Fast Digestion Spectrophotometric Method", HJ 535-2009 "Water Quality - Determination of Ammonia Nitrogen - Nessler's Reagent Spectrophotometric Method", HJ 671-2013 "Water Quality - Determination of Total Phosphorus - Ammonium Molybdate Spectrophotometric Method" and HJ 636-2012 "Water Quality - Determination of Total Nitrogen - Alkaline Potassium Persulfate Digestion UV Spectrophotometric Method". It enables rapid determination of dozens of concentration parameters in water such as COD, ammonia nitrogen, total phosphorus, and total nitrogen. The instrument features intelligent data analysis with both chart and list display modes for at-a-glance interpretation; an 8-inch high-definition color LCD touch screen, Android smart operating system, Chinese display interface with Chinese/English soft keyboard, and user-friendly operation. Paired with a 28-hole intelligent dual-temperature-zone digester, it enables rapid outdoor testing with even simpler operation.

II. Applications
