Compact Fluorometer for Long-term Monitoring of Photosynthesis

See the MICRO-PAM in action

On June 10, 2026, after 7 years of recording photosynthesis of trees, a new experiment was started. Now, our monitoring station at the Walz headquarters streams live chlorophyll fluorescence data from ivy (Hedera helix). Five MICRO-PAM fluorometers continuously record photosynthetic yield, light intensity, temperature, and humidity - 24 hours a day, 7 days a week.

Three types of live graphs are available: Y(II) + PAR, Y(II) + ETR, and Temperature + PAR + Humidity. Data can be downloaded and displayed using the WinControl-3 software.
