Fluorometers (oil in water, CDOM, rhodamine & chlorophyll A)

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).
• Self-cleaning: unique hydrophobic nano-coating of lenses with a choice of additional cleaning options:
  • TriOS AirShot self-contained compressed air system (or use air from your site) - YouTube demo
  • Zebra Tech brush cleaning system with self-contained or datalogger triggered mechanism - YouTube demo

  • sea, river or freshwater reservoir systems
  • incoming / outgoing flow at drinking & wastewater treatment plants
  • potential filter membrane leaks during rhodamine testing
• Internal reference signals of the high performance LEDs used for fluorescence excitation compensate ageing effects and temperature influences.
• G2 interface
• Self-cleaning: unique hydrophobic nano-coating of lenses with a choice of additional cleaning options:
  • TriOS AirShot self-contained compressed air system (or use air from your site) - YouTube demo

TriOS matrixFlu UV optical fluorescence measurement sensor

• This 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.
• Self-cleaning: unique hydrophobic nano-coating of lenses with a choice of additional cleaning options:
  • TriOS AirShot self-contained compressed air system (or use air from your site) - YouTube demo
  • Zebra Tech brush cleaning system with self-contained or datalogger triggered mechanism - YouTube demo

TriOS microFlu CDOM, chlorophyll or cyanobacteria miniature fluorometer

• Discontinued - see nanoFlu above
• Used for: CDOM, chlorophyll or cyanobacteria miniature fluorometer
• microFlu fluorometers are low-cost, miniature and submersible for high precision, selective measurement of CDOM (Coloured Dissolved Organic Matter), chlorophyll-A or cyanobacteria. The combination of low power consumption, innovative nano coating as energy and environmental neutral fouling protection and longterm stability makes it suitable for monitoring in rivers, lakes, seawater and for all applications in the field of water quality and wastewater monitoring.
• Internal reference measurement of the emitted light compensates aging effects of the high-efficient LEDs, used for fluorescence excitation.
