Overview

After adding potassium persulfate to the water sample to be tested and dissolving it at high temperature, ascorbic acid is added to the acidic medium to form a blue complex. The instrument measures the absorbance value after fixed wavelength irradiation to convert the total phosphorus content.

Product Details

·Product Overview

This instrument is designed and manufactured in accordance with the national standard "Determination of Total Phosphorus in Water Quality - Ammonium molybdate spectrophotometric method (GB 11893-1989)" and the technical requirements of water quality online automatic monitoring instrument. It adopts the latest optical metrology, high-temperature and high-pressure digestion, digestion colorimetric integration and other technologies, and has the characteristics of accurate measurement, low detection limit, high reliability, and strong adaptability. It is widely used in environmental protection, production monitoring and other fields, and is an ideal instrument for environmental monitoring and control.
