Applications for MICRO-PAM

Live Data

On October 17, 2024, after 5 years of recording photosynthesis in cherry laurel leaves, a new period of long-term monitoring was started. The pilot experiment combines PAM fluorescence analysis and sap flow measurements. An Arizona cypress tree (Hesperocyparis arizonica) is being investigated.

A MICRO-PAM system including four fluorometers provides live data via a WiFi modem. Three 3 types of live graphs are available (see below): Y(II) + PAR, Y(II) + ETR, and Temperature + PAR + Humidity. Data can be downloaded and displayed using the WinControl-3 software. Import of sap flow data into the WinControl-3 software is under development.
