PA-2 / PA2-Gold

MERCURY ANALYZER FOR WATER AND AQUEOUS SOLUTIONS IN PROCESS APPLICATIONS

The mercury analyzer PA-2 is used for continuous monitoring of mercury concentrations in industrial processes. The PA-2 was specially designed for process analysis and operation under harsh industrial condition. The system comes with either the VM-3000 or the UT-3000 photometer to meet different requirements regarding accuracy and sensitivity of measurements.

FEATURES AND BENEFITS

  • Fully automatic system
  • Easy menu-driven operation
  • Proven and reliable detection method: AAS
  • Measuring ranges from 10 ppt to 100 ppm
  • High flexibility of sample pretreatment
  • Suited for complex sample compositions
  • Low reagent consumption
  • Corrosion-protected construction
  • Automatic self diagnosis system for reliable operation

MAIN APPLICATIONS

  • Quality control in chlorine-alkali plants
  • Monitoring of scrubber water of waste incinerators and power plants
  • Control of industrial sewage
  • Control of purification plants
  • Quality control of sulphuric acid
  • Quality control of drinking water
