AlgaeGuard
Continuous Chlorophyll Measurement
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
