Measurement Principle

lUses a sapphire valve core ten-way valve with high wear resistance coefficient, 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 slight contamination do not affect the measurement value;

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

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

lIncludes 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 functions;

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

lEquipped with overheating protection: automatically cuts off power to the heater when 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 analysis instrument process log, 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.
