TOC analyzing system, TOCOR700


The TOC analyzer system TOCOR700 oxidizes the organic carbon in the water sample to CO2 which is then measured by an NDIR gas analyzer. Anorganic carbon which would falsify the analysis is previously removed by a stripper. The required carrier gas is produced by the TOCOR700 itself, so it can be operated independently from instrument air. A back-flushing filter unit for turbid water samples and a dilution unit for samples with high salt loads are available as options. The TOCOR700 is available in two versions:

  • TOCOR700 TH with a thermal high-temperature reactor is especially suitable as a precise analyzer device for unknown water contaminants
  • TOCOR700 UV with its UV reactor can be used for monitoring of limits or in case of known water contaminants.

    At a glance

  • Very high measurement accuracy with small TOC concentrations
  • Generates its own carrier gas
  • Sample point switching for up to 4 sample points as an option
  • Versions for application in Ex-zone 1 or 2 (ATEX)
  • Versions as stand-alone device or as wall cabinet

    Your benefits

  • TOC determination according to legal specifications
  • No need for expensive carrier gas
  • Two reactor types for selection, depending on application requirements
  • Second thermal reactor as an option offers reduced downtimes for maintenance

    Fields of application

  • Monitoring in waste water treatment plants
  • Monitoring of surface water
  • TOC monitoring of waste water
  • Monitoring of condensate in cooling circuits
  • Contamination monitoring of process water
