Measurement Principle

lUses a sapphire valve core ten-way valve with high wear resistance, resistance to strong acids and alkalis, organic solvents, long service life, and high stability;

lEmploys a specially designed reference method, where minor displacement of the digestion cell and minor contamination do not affect measurement values;

lFeatures waste liquid separation function, enabling separate discharge of high-concentration reaction waste and low-concentration cleaning waste;

lIncludes dynamic dilution function, automatically adjusting dilution ratio based on the on-site set range;

lHas built-in quality control functions such as spiked recovery, blank testing, standard sample verification, zero point verification, span verification, parallel sample testing, and supports automatic, manual, and remote initiation of quality control;

lCapable of automatic fault diagnosis and uploading/recording of abnormal information, such as component failure, over-range alarm, exceedance alarm, reagent shortage alarm, etc.;

lIncludes overheating protection: automatically cuts off power to the heater if the temperature is too high;

lAfter abnormal reset or power restoration, the instrument automatically discharges residual reactants and returns to the initial working state. Features power-on alarm function, generating an alarm message upon restart after power loss;

lHas process logs, measurement data recording, and alarm information storage functions. With data recorded hourly, it can store over 3 years of data and supports quick export via USB drive;

lFeatures three-level management permissions;

Typical Applications

lOnline monitoring of ammonia nitrogen concentration in drinking water and surface water;

lOnline monitoring of ammonia nitrogen concentration at municipal sewage inlets/outlets, pollution source discharge points, and industrial wastewater outlets.
