The WATER-PAM-II is next to PHYTO-PAM-II, the instrument of choice for phytoplankton analysis. It can be used for laboratory cultures as well as natural water samples when very low chlorophyll contents of samples require ultra-sensitive fluorescence detection.
The WATER-PAM-II is a portable cuvette system for analysing the photosynthetic activity of a wide variety of phytoplankton samples. The light weight instrument offers a wide range of applications thanks to its large sensitivity spectrum, the ability to easily switch between red or blue light mode (measuring light and actinic light) and a variety of accessories such as a flow-through cuvette.
