On-line Water Quality Analyzer 4110 Series

TOCN-4110 On-line TOC/TN Analyzer

TOCN-4110 On-line TOC/TN Analyzer

The TOCN-4110 is a compact, unique water quality analyzer allowing both TOC analysis by the combustion oxidation / infrared detection method, and TN analysis by the combustion / chemiluminescence detection method, all in a single unit.

Features

  • The TOCN-4110 is a compact, unique quality analyzer allowing both TOC analyses by combustion oxidation / infrareddetection method and TN analysis by the combustion / chemiluminiscence detection method in a single unit.
  • TOC and TN are simultaneously measured and results obtained in as little as 4 minutes.
  • For TOC measurements all known measurements methods (TC,NPOC (standard) TOC=TC-IC (option), TOC=POC+NPOC(option)) are available.
  • For TOC a wide measurement range is variable from 0-5ppm full scale to 0-1000 ppm full scale. Measurements up to 20,000 ppm are possible using on-board dilution function. The TN measurement range is from 0-1 ppm to 0-200 ppm, with the dilution function up to 4000 ppm.
  • Automatic dilution expands the analysis range and allows the reduction in salt, acid, and alkali concentrations to help reduce maintenance and extend catalyst life.
  • A complete line of options designed to accommodate samples with suspended particles, reduce remedial maintenance in on-line TOC/TN measurement. 3 type of sample pretreatment units are available.

  • Automatic calibration is incorporated using standard solutions stored on-board. Automatic calibration is possible even when using the on-board dilution function.
  • On-board carrier/combustion gas purification allows use of air supplied from a compressor, thus eliminating expensive and potentially dangerous cylinder gases.
  • Various input/output and alarm function allows a complete control via control station.

Applications

  • Management of influent and effluent water for wastewater treatment.
  • Management of various plant waters. (i.e.: washing, rinsing, cooling, circulating, boiler, condensate, and other plant liquids)
  • Monitoring of drinking water (source water, in-process water), highly processed water.
  • Monitoring of surface water (rivers, lakes and streams)_
  • Water quality monitoring for regulatory reporting
