PHYTO-PAM-II/ED (Compact Version)
PHYTO-PAM-II COMPACT version features a five-wavelength phytoplankton and photosynthesis analyser providing de-convolution of up to four differently pigmented groups of algae (green algae, diatoms, cyanobacteria and phycoerythrin containing organisms).
The instrument holds control unit and measuring chamber in a single compact design well suitable for on-deck and field applications.
Due to the outstanding optoelectronic characteristics, five measuring light wavelengths, six actinic light colors and a highly sensitive photomultiplier detector PHYTO-PAM-II features classical PAM analyses, measurements of wavelength-dependent aspects of photosynthesis , fast kinetics measurements with high time resolution to measure O-I1 fluorescence rises as well as evaluation of the functional absorption cross-section of PSII (σPSII).
Therefore PHYTO-PAM-II opens up new aspects in algal research.
