Measurement Principle

Features

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

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

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

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

lIncludes built-in quality control functions such as spike 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.;

lEquipped with overheating protection: automatically cuts off power to the heater when temperature is too high;

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

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

lIncludes three-level management permissions.

Typical Applications

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