Double-Modulation Fluorometer FL 6000 measures chlorophyll α (Chlα)- -?uorescence. Measured ?uorescence emission is excited by a set of light- -emitting diodes that generate measuring ?ashes of few microseconds in duration and low intensity; the photochemistry is driven by single-turnover ?ashes or by continuous actinic irradiance. Chlorophyll ?uorescence is detected by a PIN photodiode and digitized by a 16-bit A/D converter. The instrument supports Pulse Amplitude Modulation measurements and, at the same time, can capture fast OJIP transients or perform rapid measurements of QA- reoxidation kinetics, S-states.

Algae Online Monitor (AOM) is a portable and robust device for online detection and continuous monitoring of photosynthetic microorganisms in both natural and artificial water bodies. It detects variety of cyanobacteria, green and brown algae, diatoms, and other microbes.
