  • Low reagent consumption
  • Easy handling
  • Highly reliable
  • High accuracy
  • Robust design

The instrument applies a method derived from DIN EN ISO 6878 using a UV digestion with peroxodisulphate and sulphuric acid followed by the photometric yellow method. This method is highly recommended by German wastewater association DWA.

A wide measuring range up to 50 mg/l is covered with high accuracy. The maximum measuring range can be reached without manual changes to the instrument settings or recalibration. This makes PHOSPHO highly reliable for detecting irregularities. Eco-Save feature: automatic adjustment of the reagent dosage to the actual measuring value can further reduce the low reagent consumption.
