The product complies with JJG631-2013 Ammonia Nitrogen Automatic Monitor, environmental standards HJ536-2009, HJ/T 101-2003 Technical Requirements for Ammonia Nitrogen Water Quality Automatic Analyzers, Q/WTH48Y TH-2023 TH-ZX200 Automatic Ammonia Nitrogen Water Quality Analyzer.
Application Scope
The TH-ZX200 automatic ammonia nitrogen water quality analyzer is a device independently developed by our company for measuring ammonia nitrogen concentration in water. It is suitable for online and offline detection of surface water, pollution source water quality, industrial and municipal wastewater, and sewage.
Instrument Principle
In alkaline medium (pH = 11.7) with sodium nitroprusside present, ammonia and ammonium ions in water react with salicylate and hypochlorite ions to form a blue compound. The absorbance is measured at 660 nm and converted to ammonia nitrogen concentration in water.
Instrument Features
•Uses imported photodetector with very high sensitivity;
•Uses high-precision syringe pump combined with multi-way valve for very high reagent injection accuracy;
•Unique technology subtracts the influence of water turbidity and color, stable operation;
•The instrument has online, offline, timed, and fixed-point measurement functions, set according to user needs;
•The instrument has automatic cleaning, manual cleaning, and fixed-point cleaning functions;
•The instrument has automatic calibration, automatic zero point, standard sample verification, and spiked recovery functions;
•The instrument has self-diagnostic function, alarm prompts, easy maintenance;
•The instrument has remote control function, realizing remote transmission, monitoring, and inspection of instrument working parameters, status, and data, supporting remote calibration, remote verification, and remote spiked recovery;
•The instrument's built-in refrigeration system makes reagent storage time longer and more stable;
•Low reagent and waste liquid usage, small maintenance amount, long maintenance cycle, few parts replacement, easy replacement;
•Chinese interface display, touch screen design, simple operation, powerful functions;
•Large amount of data stored for a long time, data not lost on power failure;
•Rich communication interfaces, communication protocol fully compliant with relevant standards of the Ministry of Ecology and Environment;
•Automatic protection on power/water failure, parameter saving, auto-start on power restoration.
