The quick-and-easy portable measuring instrument. Switch on, dip in, read off. The bbe AlgaeTorch is a handy instrument for the measurement of microalgae and cyanobacteria in all types of water, both fresh and saline. The AlgaeTorch measures chlorophyll-a of intact cells without sample preparation. A complete measurement needs less than 20 seconds. No sampling or preparation is necessary.
Automatic turbidity compensation: Suspended particles in the water affect the chlorophyll determination. The built-in turbidity measurement compensates for such effects automatically. The benefit is the simultaneous turbidity correction during chlorophyll measurement which makes subsequent correction unnecessary, improves the accuracy and enables the evaluation of the results at site. The turbidity value is shown in the display.
- The Measurement Principle
Measurement of algal concentrations via fluorescence
The bbe AlgaeTorch uses in vivo fluorescence of algae cells: the algae pigments are selectively excited by coloured LEDs and emit red fluorescence light as a natural phenomenon. The intensity of the chlorophyll fluorescence is used to determine all phytoplankton as chlorophyll-a, here blue-green algae (cyanobacteria) and total microalgae. The calculation is based on the calibration of the AlgaeTorch with real microalgae. The result is shown immediately on the display and stored in the internal memory. An encapsulated USB port enables subsequent data transfer to a PC. The PC software is supplied free of charge.
