Eijkelkamp spectrometer (UV/VIS)

Real-time optical measurement of BOD, COD, TOC, NO3 and many others…

The Eijkelkamp spectrometer is an optical instrument for the continuous measurement of multiple parameter directly in the medium. Using full spectral information, it determines organics (COD, BOD, TOC, UV254), nitrate, turbidity, suspended solids, and many more, with a single device. Advanced algorithms provide accurate and reliable readings, and eliminate interferences (e.g. turbidity).



  • Wastewater treatment plants (influent, effluent, process control)
  • Industrial application (process water, wastewater treatment)
  • Wastewater collection systems (load monitoring, corrosion protection)
  • Water reclamation, reuse and irrigation
  • Environmental Monitoring (surface water monitoring)
  • Aquaculture and fish farming
  • Landfill leachate monitoring
  • Drinking water (source monitoring, process control, early warning of contaminations)
  • Ground water management
  • more…

Real-time results, directly from the process

  • Real time sensor
  • In-situ installation (no sampling or sample pretreatment)
  • 100% optical (no reagents, long term stable, simple to use)
  • Small size sensor probe (allows in-situ and in-pipe installations)
  • Minimal operating costs (no consumables, automatic cleaning, minimal maintenance)

Highly Robust

  • Suited for high temperature applications (0 – 110oC)
  • Available in both stainless steel and titanium, quartz windows
  • Full spectral measurement for high specificity and compensation

Unparalleled Flexibility

  • Multiple parameters from one device
  • Software supports development of own parameters and virtual sensors
  • Variable pathlength – measurement range can be adjusted to the matrix
  • Standard ATEX certification class III (ATEX class II optional)
  • Wide range of communication interfaces
  • Controller with full PLC functionality
