Product details

Total Phosphorus Online Water Quality Analyzer (TP)pickUsing spectrophotometric analysis, the detection range standard is 0.02-200mg/L, and the range can be expanded according to the actual water sample. Firstly, potassium persulfate (or nitric acid perchloric acid) is added through a peristaltic pump to dissolve and oxidize the unfiltered water sample into orthophosphate. Then, ammonium molybdate is added dropwise for color reaction, and ascorbic acid is used to reduce it to a blue complex. The absorbance is detected at a specific wavelength. The instrument automatically calculates the concentration of orthophosphate in the water sample based on the built-in curve.
