The new WATER-PAM-II Chlorophyll Fluorometer is a small portable instrument for phytoplankton research and water analysis. The WATER-PAM-II is a major upgrade to our popular WATER-PAM, including multicolor LEDs for determining algal composition and extended operation on standard AA batteries. Ideal for HAB field research.

Detecting variable fluorescence of PSI has been challenging because of the spectral overlap of PSII and PSI fluorescence. The versatile configuration of the MULTI-COLOR-PAM has allowed detection of PSI fluorescence using filter sets for long and short wavelength components of chlorophyll fluorescence. Drs. Schreiber and Klughammer report persuasive evidence of variable PSI fluorescence in green algae, cyanobacteria and green plant.
