Get to know your water… with bbe Moldaenke

For more than 10 years now, bbe Moldaenke GmbH has been one of the leading manufacturers of top-quality products in environmental technology. bbe develops and produces measuring instruments and software to assess and manage water quality. Their instruments are made for use in oceanography, limnology, drinking water monitoring, river dam monitoring, bathing water analysis, supervision of aqua culture systems and environmental assessment. To learn more about these products and to determine which instrument best suits your application, please get in contact with PP Systems to speak to a products specialist. We look forward to being of assistance.

AlgaeTorch

Measurement of cyanobacteria with the AlgaeTorch from bbe Moldaenke

In-situ measurement of cyanobacteria has never been easier…. Power up, submerge and measure!

Close-up of AlgaeTorch LCD

It’s as simple as that and all in less than 1 minute!

The AlgaeTorch is lightweight, field portable and designed to measure total chlorophyll and blue-green algae (cyanobacteria).  The pigments of the algae are spectrally excited subsequently by three colored LEDs at a high frequency.  In response, the algae emit red fluorescence light and the intensity of this light is used for calculation of the different algae types (i.e. blue-greens and total micro-algae).  Results are displayed and stored in the internal memory and can easily be transferred to a PC via the USB port for further analysis.

Fluoroprobe

Fluoroprobe from bbe Moldaenke

Applications

  • Drinking water monitoring for blue-green algae (cyanobactria)
  • Supervision of aquaculture systems
  • Control of bathing water for toxic blooms
  • Early warning system
  • Ocean/lake research
  • Limnological research
  • Education

A unique in-situ spectrofluorometer which provides accurate measurements of up to 5 different algae classes and total chlorophyll in one portable unit.

The FluoroProbe quickly and reliably determines chlorophyll concentration down to depths of 100 meters making it an ideal instrument for depth profiling.  The measurements can be displayed on-line via a serial interface or stored in the probe for subsequent analysis.  In addition to determining the chlorophyll content, the probe also detects the presence of algae and allocates them to various spectral algae classes (i.e. blue-green algae/cyanobacteria, green algae, diatoms/dinoflagellates/chrysophytae, cryptophytae).  This enables the instrument to analyze the occurence and distribution of algae on site without the necessity of the laboratory.

Measurement Chamber

NEW! Depth-profile with quick analysis of chlorophyll and unbound phycocyanin concentrations as well as algae classes

The bbe PhycoProbe* is a highly sensitive measuring instrument for the in vivo analysis of chlorophyll-a in real microalgae and blue-green algae (cyanobacteria). Individual profiles for the different algal classes are created during the measurement. The algal content is determined by evaluating the chlorophyll fluorescence in real time. Without the necessity of using a laboratory, it is possible to completely analyse the occurrence and distribution of algae in different water bodies, if necessary at different depths.

Additionally, the PhycoProbe measures the amount of unbound phycocyanin (free PC) which reflects the release of blue-green algae contents like toxins as well as flavours and odorous substances. Interference from e.g. humic substances is compensated using the integrated yellow substances measurement.

Hydro-Wiper unit to prevent biofouling

The PhycoProbe can now be operated on moored platforms, submersed from buoys or fixed measuring stations using the Hydro-Wiper (made by Zebra-Tech Ltd, NZ). The wiper brushes can be set to periodically clean the lenses of the measuring chamber to remove biofilms and dirt which builds up over long periods of operation.
