OverviewPhosphate (PO4) measurementSpecificationsResources

Monitor AMI Phosphate Boiler having complete monitoring system for the automatic, continuous measurement of ortho-phosphate in boiler water.

  • Measuring range: 0.01 to 10 ppm (mg/L) PO4
  • Based on colorimetric measurement principle.
  • No interferences with silica.
  • Complete system including measurement and control electronics, photometer, flow indicator, reaction chamber, reagent dosing system and reagent containers.
  • Measurement values are available as analog output signals.
  • Alarm display and activation of alarm relay when user defined, critical limits are reached.
  • Continuous, automatic monitoring of main in-strument functions (sample flow, reagent supply).
  • Large back-lit LC display showing all measured values and status information simultaneously.
