:: Product Information



Distinction of green algae, blue-green algae (cyanobacteria), diatoms and crytophytes in a flow-through chamber - simple, quick and reliable

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.

Measurement using the AlgaeGuard

  • direct chlorophyll fluorescence
    corresponds to wet-chemical chlorophyll analysis

  • spectral algae classes
    to simultaneously determine the content of chlorophyll according to green algae, blue-green algae, brown algae (diatoms and dinoflagellates) and cryptophytes

  • transmission
    parallel to chlorophyll measurement during each analysis, allows the compensation of the influence of substances which cause turbidity

  • yellow substances concentration (CDOM)
    influences the chlorophyll result due to its fluorescence; to improve the chlorophyll measurement, the yellow substance content is determined and used automatically for the chlorophyll correction

  • water temperature
