Spectral-8 or Real-time Optical Measurement of BOD, COD, TOC, NO3

The Spectral-8 spectrometer UV/Vis 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). Fully integrated in the Eijkelkamp Web Portal for online visualization of measurement results and integration with your other monitoring solutions. Supports remote calibration and device configuration.


  • 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

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)
