Question
What parameter do the Phosphax sc, Series 5000, and 5500 sc Phosphate Analyzers Measure?
Summary
Phosphax sc, Series 5000, and 5500 sc Phosphate Measurements
Answer
The Hach online phosphate analyzers measure ortho-phosphate ions (PO43–); di-phosphates and polyphosphates are not measured. 

Note: The Series 5000 and 5500 sc Phosphate analyzers only have the option to display PO 4 and there is no option in the menu to convert that result to PO 4 -P. It is important to be mindful of the units the measurements are being expressed in when comparing lab and process measurements as they may differ. Please see the attached document for more information.
