TOC Analyzers

TOC-4110

TOC is used in a variety of applications from management of wastewater treatment plant influent and effluent, to drinking water supply management and monitoring of impurities in process and natural waters. And the range of applications in which this type of on-line technology is used is expected to continue expanding.

Features

  • High-performance on-line TOC analyzer using the established 680°C catalyst-aided combustion and non-dispersive infrared detection methods.
  • Wide measurement range is variable from 0-5ppm full scale to 0-1000ppm full scale. Measurements up to 20000ppm are possible using the on-board dilution function.
  • Measurement mode selectable between TC/NPOC (standard), TOC=TC-IC (optional) or TOC=POC+NPOC.
