Measurement PrinciplePrinciple

Ammonium molybdate spectrophotometry. In an acidic medium, orthophosphate reacts with a chromogenic agent and a reducing agent to form a colored complex. The absorbance is measured at a specific wavelength, which is proportional to the concentration of orthophosphate.

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

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

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

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

?Includes 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;

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

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

?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;

?Has process log, measurement data recording, and alarm information storage functions. With data recorded hourly, it can store over 5 years of data and supports quick export via USB drive;

?Features three-level management permissions.

Typical ApplicationsApplication

?Online monitoring of orthophosphate in drinking water and surface water;

?Online monitoring of orthophosphate in municipal sewage outlets, pollution source discharge points, industrial wastewater outlets, secondary sedimentation tanks, and high-efficiency sedimentation tanks.
