Mainly based on the colorimetric method in photometry, phosphate ions react with specific reagents to form colored phosphomolybdate complexes. The instrument determines the phosphate concentration by measuring the light absorption of the solution at specific wavelengths. It can provide accurate and reliable phosphate concentration data, offering scientific support for water quality monitoring.
