Total Phosphorus Analyzer

Total Phosphorus Analyzer

Model:FT-SZZL

Brand:fengtu

Total Phosphorus Analyzer is suitable for monitoring the total phosphorus content in surface water, municipal sewage and industrial wastewater.

Product details

1.Total Phosphorus Analyzer Principle

Total Phosphorus Analyzer is suitable for monitoring the total phosphorus content in surface water, municipal sewage and industrial wastewater.Under high temperature and high pressure conditions, the sample is digested with potassium persulfate, and all phosphorus compounds in the sample are converted to orthophosphate (this step is not required for measuring orthophosphate). In a 5%-8% nitric acid solution, orthophosphate forms a soluble phosphorus-vanadium-molybdenum yellow complex with ammonium metavanadate and ammonium molybdate, and its absorbance is measured at a specific wavelength. The absorbance is linearly related to the orthophosphate concentration of the sample. Based on this relationship, the absorbance can be converted into the total phosphorus (TP) or orthophosphate (PO4) concentration value of the sample.

2. Product Features of Total Phosphorus Analyzer

The new photoelectric quantitative technology is not affected by interference such as large chromaticity, large amounts of suspended matter, and large amounts of bubbles. It has high reliability and accuracy and strong anti-interference ability.

High detection accuracy, low measurement limit and small long-term drift of the instrument.

It has one-button self-test function and self-diagnosis function.

Adopt single-channel highly integrated valve group, maintenance and cleaning are simple and quick.

All-weather networking function, monitor the instrument operation status anytime and anywhere.

It has alarm function, quality control function and reverse control function.

It has automatic cleaning and automatic calibration functions.

It has functions of hourly measurement, interval measurement and external control measurement.

It will work automatically after power failure.

Automatic prompt and automatic reset function for fault and reagent (sample) shortage.

With fault recording function.

Can save historical data for more than 3 years.

Meet the requirement of separate discharge of cleaning liquid and waste liquid
