The AlgaeOnlineAnalyzer: Real-time 24/7 online detection of chlorophyll concentration, algae classes & photosynthetic activity.
bbe Moldaenke GmbH has developed and produced measuring instruments and software to assess and manage water quality for more than 20 years. Made for use in oceanography, limnology, drinking water monitoring, river dam monitoring, bathing water analysis, supervision of aqua culture systems and environmental assessment, these instruments have come to be relied upon as the industry standard. 
The ideal solution for online, flow-through measurement of microalgal concentrations in rivers, lakes and reservoirs

The AlgaeOnlineAnalyzer continuously determines the algal content of water based on chlorophyll fluorescence in real time and without the need for sample preparation. The chlorophyll-a measurement is used as an approximation of the biomass of the micro-phytoplankton in the water.
The measurement is based on the natural fluorescence of the photosynthesis apparatus of chlorophyll using excitation by light sources. Comprehensive excitation of all microalgae is made possible by six different LEDs at particular frequencies.

Low Maintenance
The AlgaeOnlineAnalyzer uses a cleaning mechanism in the measuring chamber ensuring the removal of particles and biofilms inside the chamber.

Biofilms can reduce the excitation light and lead to poor measurement results.
A regulated inflow of sample water enhances the versatility of the AlgaeOnlineAnalyzer. A valve switches alternatively between two tubes of the Analyzer enabling the user to take water samples from different depths or locations, and measures algae chlorophyll online at high frequency.

The records allow the user to draw conclusions about the success of the measurements in order to reduce or enhance microalgae in process water, cooling water or a culture.
The AlgaeOnlineAnalyzer is calibrated using real algal cultures, needs no sample preparation and can even replace the laborious method of cell counting with a microscope.
Advantages of the AlgaeOnlineAnalyzer
