Shandong Dongrun Instrument Science And Technology Co., Ltd.
CHNH-812 Portable Ammonia Analyzer
The instrument uses Nessler colorimetric measurement of ammonia in the water, the method is simple and high sensitivity. The principle is: ammonia or ammonium ions exist in the free state and sodium's reagent to generates yellow-brown complex, the complex is proportional to the chromaticity and ammonia content.
