Rapid and simple algae monitoring The Instrument for Depth Profiles of Microalgae Suitable for all surface waters: lakes, reservoirs, rivers and bathing water

What can the FluoroProbe III do? The FluoroProbe III is a depth profiler for the rapid detection of chlorophyll-a in phytoplankton Water FEATURES ▶ Scientific analysis of water quality ▶ Qualified measurement of chlorophyll-a ▶ Simultaneous measurement of different algal classes ▶ Detection of cyanobacteria ▶ Depth profiling in real time ▶ Evaluation of algal blooms ▶ Detection of phytoplankton populations as the basis of life of all organisms has an essential significance. Increasing anthropogenous pollution of water bodies requires an increase in the observation and assessment of water...

How does the FluoroProbe III measure chlorophyll-a content? Photosynthesis uses the light energy of the sun to gain and convert energy into energy-rich substances. This process is closely linked to the photosystems of algae and cyanobacteria – with chlorophyll-a playing a central role in the conversion. Fluorescence – i.e. the emission of previously absorbed light – is a natural process. When energised by sunlight or artificial light, unused or superfluous energy is immediately given off. The light-collecting photosystem emits red light at a wavelength of 685 - 700 nm, which is detected by...

FEATURES ▶ Calibration using algal cultures ▶ Temperature sensor ▶ Depth sensor bbe FluoroProbe III emission lights This is helped by a determination of yellow substances and an automatic correction. The spectral characteristics of yellow substances are stored in the FluoroProbe III and can be adapted to a specific location when necessary. This also applies to algae with particular spectral characteristics: a calibra tion to a new algal class extends the range of application and increases the accuracy of the allocation of the algal classes. The advantage lies in the use of real algae for...

The FluoroProbe III is readily deployable without cable by use of an autostart plug. By attaching the plug, the measurement is started and continues until the plug is removed. Via a measurement cable or the USB adapter the data can be transferred to a PC or the USB flash drive supplied. The depth range of the FluoroProbe III is down to 200 m. The internal battery supplies the FluoroProbe III for extended underwater operation without an external power source. For longer operation bbe recommends the setting for sleep mode with low power usage and an optional wiper for the removal of biofilm...

The spectral analysis of algae Chlorophyll-a content from algae and cyanobacteria ▶ Reference spectra ▶ Fit procedure Bluetooth-Set with smartphone for data viewing and control BBE++ SOFTWARE ▶ Database ▶ Graphic and table representation ▶ Macro settings ▶ Basic and expert modes ▶ Re-calculation ▶ Data export How is the chlorophyll-a calculated? The FluoroProbe III is prepared for immediate chlorophyll determination by factory calibration using standard algae. This is performed using a special spectrofluorometer (bbe ALA) which has been calibrated using HPLC analyses of extracted algal...
