The spectro::lyser is a fully submersible spectrometer instrument that uses the power of light to measure up to 8 water quality parameters simultaneously.


The spectro::lyser is ideally suited for a wide variety of monitoring requirements ranging from ultra-pure water applications to the harsh environments of wastewater monitoring applications.

    • A wide range of parameters can now be monitored continuously, including nitrate, nitrite, ozone, colour, turbidity, TSS and organic parameters such as COD, BOD, TOC and DOC.
    • By including additional sensors into the system further parameters can be derived, such as calculating the chlorine demand needed to treat the water (with the inclusion of the chlori::lyser) or H2S (with the inclusion of a pH sensor).
    • Gives full spectral fingerprint of the monitored water.
    • Software is able to correct for many cross-sensitivities, ensuring high accuracy and reliability in its results.
    • Software can trigger an alarm if unusual changes in the water is measured.
    • Software can re-evaluate collected spectra if a bad calibration was used. Allows historical data to be re-examined for new contaminants in future calibrations.
    • Long-term stability.
    • Minimal maintenance required.
    • Auto-cleaning options allow for long-term deployment with minimal oversight.
    • Factory pre-calibrated with a Global Calibration specific to your application.
    • Can be mounted either directly in-stream (in-situ) or in a flow-cell/bypass.
    • Contaminant alarms based on the spectral fingerprint to detect unidentified pollutants.
