Multiphase Flash Fluorometer
The Multiphase Flash™ Fluorometer (6800-01) is a combined light source and chamber for simultaneous measurements of gas exchange and chlorophyll a fluorescence from the same 6-cm2 leaf area. The light source includes a Pulse Amplitude Modulated (PAM) fluorometer, which provides a highly uniform light field over the leaf surface. Capable of saturation flash intensities up to 16,000 µmol m-2 s-1, the fluorometer measures dark-adapted (Fo, Fm, Fv/Fm) and light-adapted (Fs, Fm’, Fo’, ETR) parameters, as well as induction kinetics (OJIP). Supports the Multiphase Flash Fluorescence protocol to accurately extrapolate Fm’ in leaves that are difficult to light saturate.
