NHNG-001 Type Portable Ammonia Nitrogen Meter
Product Description: this instrument by Nessler's colorimetry to measure the water ammonia nitrogen, the method has simple operation, high sensitivity characteristics. The principle is: exist in the free state of ammonia or ammonium ion in the form of ammonia and sodium reagent reaction to produce yellow brown complex. The content of color and ammonia nitrogen in the complex is proportional to.
