MINI-PAM-II

Introduction to the instrument, accessories, and applications of the MINI-PAM-II.

WATER-PAM-II

WALZ has just introduced the new WATER-PAM-II Chlorophyll Fluorometer, 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. Key features of the new WATER-PAM-II include:

  • Broad sensitivity range, from lab cultures to natural surface and seawater samples
  • Multicolor LEDs allow measurement of green, brown and blue-green algae composition
  • Both red and blue measuring lights in one instrument for photosynthesis determination
  • Comprehensive SAT-Pulse analysis, program routines and graphical display
  • Very long field operating time utilizing standard AA-batteries
  • Optional Flow-Through Cuvette, Barcode Scanner, and Controllable Stirrer
IMAGING-PAM Mobile Version

An advanced method to create three-dimensional plant images has been added to the MAXI version. This new configuration opens the way to project data of fluorescence analysis on the three-dimensional plant image so that photosynthesis can be analyzed in the context of whole plant architecture. Newly introduced is a field portable IMAGING PAM that is designed for turf and small plant measurements. Fully battery operated and portable, it is useful for imaging field crops.

MULTI-COLOR-PAM used to detect variable fluorescence of Photosystem I

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. The open source article can be found here.
