Model FL200 -On-line Fluorometer

Based on UV or visible fluorescence, a wide range of applications can be covered by the FL200 depending on the optical head used:

• FL200-C: Chlorophyll A
• FL200-H: PAH (aromatic hydrocarbons) in water (BTEX, Phenol, oil, fuel)
• FL200-R: Rhodamine
• FL200-F: Fluorescein

Using a high sensitivity photomultiplier, the FL200 can measure very low concentrations in the ppb range.

Main applications

Chlorophyll A

• River, lake, reservoir surveys
• Drinking water treatment plants
• fish farms

PAH

• River surveys
• Ground water control cleansing
• Drinking water treatment plants
• Cooling water survey

Fluorescent tracers

• Ground water contaminant studies for chemical plants
• Flow calibration of water treatment plants
• Flow measurement in streams.

Very low operating costs

• The UV spectroscopy measuring principle requires no chemical reagent or calibration solutions resulting in very low operating and maintenance costs.

Automatic cleaning system

• A fully automated cleaning system prevents the measurement flow cell from becoming dirty, giving the analyser autonomy for several weeks without maintenance.
• The cleaning solution (5% sulphuric acid) should be renewed once a month.

Built-in peristaltic pump

• When the water is not pressurised (rivers, effluents, sewage), a peristaltic pump can be added to the analyser. It is synchronized with the measurements to increase the lifetime of the tubes.

Battery/mains power supply

• For field measurements or isolated sites, a 12V built-in battery can make the analyser autonomous for about 100 measurements.
• For plant applications, the battery provides total immunity against mains disturbances or power cuts, even over a long period.

Built-in datalogger

• The measurements are dated and stored in a static memory with a capacity of more than 10,000 measurements.
• They can be tranferred later via the RS232 port on a PC without specific software using
• Hyperterminalâ of Windowsâ . The data are compatible with standard worksheets, particularly Excelâ , to obtain graphs easily.

Graphic display

• Measurements can be displayed on the graphic screen showing all data obtained during one hour, one day, one week, one month or one year.
• During the measurement cycle, a moving synoptic shows the operation sequence.

Options

• Peristaltic sampling pump
• Measurement remote command
• Modem board
