PSI - Algae Online Monitor Technical Specifications - Brochure

The Fast Fluorometer FL 3500-F has multiple novel features, first of all the time resolution of 1 µs, that enable combining PAM measurements with fast kinetic measurements of OJIP and of flash fluorescence induction. The core of the instrument is the measuring optical head containing a standard cuvette for sample suspensions (10 x 10 mm base, up to 4 ml of internal volume). The measuring head is supplied with three sets of light-emitting diodes and a PIN diode detector with 500 kHz/16-bit AD converter. Gain and integration time of the converter are software controlled. The detector can measure Chl-fluorescence signal with time resolution up to 1 µs. The instrument has two input channels.
