Measurement PrinciplePrinciple 

Formaldoxime Spectrophotometry. After digestion of the water sample, under alkaline conditions, divalent manganese ions in the sample are oxidized by dissolved oxygen to tetravalent manganese ions, which form a reddish-brown complex with the chromogenic agent. The color change is proportional to the manganese content in the sample. The absorbance is measured at a specific wavelength, and the manganese concentration in the water sample is calculated.

Main FeaturesFeatures

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

uUtilizes a specially designed reference method, where minor displacement of the digestion cell or slight contamination does not affect measurement values;

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

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

uIncorporates quality control functions such as built-in spiked recovery, blank testing, standard sample verification, zero point verification, span verification, and parallel sample testing, with options for automatic, manual, or remote initiation of quality control;

uCapable of automatic fault diagnosis and recording/uploading of abnormal information, including component failures, over-range alarms, exceedance alarms, reagent shortage alarms, etc.;

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

uAutomatic recovery after 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;

uRecords process logs, measurement data, and alarm information, with data logged hourly, storing over 3 years of data, and allowing quick export via USB drive;

uIncludes three-level management permissions;

Typical ApplicationsApplication

lOnline monitoring of manganese concentration in tap water, drinking water, and surface water;

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