WTW Analyzer TresCon®  analyzer/module for total phosphorus

Drain monitoring of municipal wastewater treatment plants for total P and monitoring of phosphorus content in natural waters

  • High measurement accuracy by automatic 2-point calibration
  • High operational safety by complete automatic monitoring
  • Blue method

The Ptot (Ptotal) module consists of two units: First, there is a chemical-thermal persulfate digestion of the sample in the digestion unit. By overpressure and an increased reaction temperature, this process is accelerated, so that very short digestion times are achieved.

After that, the total phosphorus content is measured in the analysis unit via the molybdane blue methode. The intensity of the color is used as a measure for the original concentration of the phosphate ions. It is detected and evaluated photometrically.

Please keep in mind: The Pges (Ptotal) module requires two module slots! TresCon UNO not possible!
