CHLOROPHYLL AlgaeTorch
The bbe AlgaeTorch is a light handheld measuring instrument for the
simultaneous detection of the chlorophyll-a of blue-green algae (cyanobacteria)
and the total chlorophyll-a content of all microalgae present in the
water. The measurement of chlorophyll-a fluorescence can replace laboratory
analysis. A complete measurement requires less than 15 seconds.
Sample-taking and preparation are unnecessary. With capacitive keys on
the housing the AlgaeTorch is simple and easy to use. The instrument is
robust and waterproof and can be deployed down to depths of 10 m for
short periods (AlgaeTorch 10). Using a modified plug system, the Algae-
Torch 100 can be deployed for long periods down to depths of 100 m. The
AlgaeTorch uses the in vivo fluorescence of the algal cells. The algal pigments
are excited selectively by LEDs and emit red fluorescence light as a
natural phenomenon. The intensity of the chlorophyll fluorescence is used
to determine the different algal classes, in this case blue-green algae or
the total chlorophyll of microalgae.
