The Liquiline System CA80PH is an orthophosphate analyzer for monitoring water treatment processes. The CA80PH is available in four measuring ranges, two using the standard molybdenum method (blue method; DIN EN 1189) for low range measurement down to 50 μg/L and two using the molybdate vanadate method (yellow method) for high range measurements up to 50 mg/L. Samples and analyses can be taken as often as necessary. A typical sample analysis takes 8-11 minutes depending on the method used. The analyzer automatically obtains a water sample from the process, filters it, adds the reagent, measures the intensity, and then cleans the sampling system with compressed air or water in preparation for the next test.
