Chlorophyll Measurement

A spectrofluorometer for the measurement of chlorophyll-a in water (total content) in a flow-through cell with tubing.


  • algae differentiation
  • Yellow Substances correction
  • extended sensitivity
  • transmission measurement
  • automatic cleaning device

Principle of measurement:

  • determination of prompt fluorescence and calculation of chlorophyll-a

Measuring range:

  • 0-500µg chlorophyll-a/l
  • resolution 0.05 µg/l

Operation and data exchange:

  • up to 16 4-20mA and 16 digital outputs (optional)

The AlgaeGuard is designed as a “plug and play” instrument, i.e. measurements are carried out automatically using pre-defined parameter settings immediately after boot-up or by pressing the start button on the touchscreen panel (right).

Continuous configuration by the operater is not necessary. Maintenance is as low as 1 hour per month. Parameters can be changed using the external bbe PC software if necessary.


– Quick, simple chlorophyll determination with algae class analysis

– Direct measurement without sample preparation

– Simple operation and virtually maintenance-free

– Integrated cleaning unit in measuring chamber prevents biofouling

– Touchscreen display

– PC operation with bbe AOA software


Industrial Applications

  • cooling and utility water monitoring
  • raw water for drinking water treatment
  • industrial plants

Environmental Applications

  • lake and river analysis
  • oceanographic chlorophyll monitoring
  • environmental monitoring
  • research and education

PC Software

The external software can be used with the bbe AlgaeGuard to analyse the data and configure certain parameters. The software is supplied with the instrument. Measurements can be carried out however without an external PC.

Features for measurement mode:

  • saving of data and parameters at any time
  • graphic display of all measurement values
  • online display in LAN
  • calibration of the AlgaeGuard
  • parameterisation of the measurement

Features for data evaluation:

  • evaluation of the data as text and graphics
  • adaptation of new calibrations to datasets
  • data export to EXCEL and to text files
  • print function
