TriOS enviroFlu optical oil in water (PAH) meter

  • Operating principle: fluorescence
  • Used for: PAH (polycyclic aromatic hydrocarbons) detection in water
    • Typical applications are discharge monitoring of airports and factories, leakage detection and many others.
  • enviroFlu is a new generation of high sensitive submersible sensors for oil-in-water measurement. The used UV fluorescence principle for detection is much more sensitive than any other existing detection principle, like infrared scattering, etc. This allows the detection of PAH traces in water down to single ppb levels (e.g. in drinking water or condensate applications).
  • The sensors can be used either in stationary or portable applications.
  • A new innovative nano-coating on the lenses is preventing the optics from fouling and oil-films, making the enviroFlu-HC longterm stable and virtually maintenance free.
  • In addition, the enviroFlu-HC can be used with an compressed air cleaning system. For a chemical-free check on location solid standards, so called SolidCAL's, are available.
  • On request special application requirements can be met by changing the filter combinations, possible for example is an enviroFlu-BT for determination of BTX in water.
  • The enviroFlu-BT is also available in a deepsea version for operation in water depth down to 6,000 m (enviroFlu DS).

TriOS matrixFlu UV optical fluorescence measurement sensor

  • Our high-end matrixFlu fluorometer combines multiple excitation and detection wavelengths for fluorescence measurements in a single device that boasts a highly compact design. MatrixFlu boasts extensive features that go significantly beyond what's available on the market today.
    • The special optical arrangement of excitation and detection channels enables not only single values to be determined, but also a 3x4 or 4x4 matrix of wavelength combinations, depending on type.
    • This allows quasi synchronous in-situ detection of EEMs (Emission Excitation Matrices).
  • matrixFlu is primarily designed for the detection of PAH's (polycyclic hydrocarbons), FDOM (fluorescent organic material), and tryptophan (aromatic amino acid).
  • State-of-the-art, specially selected LEDs are used for fluorescence excitation.
  • The stability of measured values is boosted by an internal temperature correction.
  • Equipped with our innovative G2 interface with web browser configuration, internal data logger, flexible protocols and data outputs,
    • The state-of-the-art G2 interface not only ensures quick integration into third-party systems, but also use of the wide range of accessories for our devices.

TriOS surFlu optical oil film on water detection sensor

  • Oil spills and related oil pollution pose a potential risk for businesses that use oils or lubricants in their processes in any way. Alongside our world-leading enviroFlu (refer separate listing) for the detection of very small amounts in water, we now offer surFlu for the detection of oil films on water.
  • State-of-the-art, stable UV LED technology for fluorescence excitation and multiple detection channels for reliable detection of smallest oil films on water enable universal application of the device. Multi-channel detection ensures reliable differentiation from biogenic films (which are caused e.g. by dead algae), foliage, humic substances, undulations, thus avoiding false alarms.
  • The special geometry of the optics allows large variance in the distance between sensor and water surface, so that even highly fluctuating water levels in basins, gullies, streams or rivers will have no impact on the measuring signal. The stability of measured values is boosted by an internal temperature correction.
  • Equipped with our innovative G2 interface with web browser configuration, internal data logger, flexible protocols and data outputs, surFlu boasts extensive features that go significantly beyond what's available on the market today. 
    • The state-of-the-art G2 interface not only ensures quick integration into third-party systems, but also use of the wide range of accessories for our devices.
