PSI's Monitoring Pen is a lightweight, portable and durable fluorometer. It is an extended version of the popular FluorPen. Its robust and weatherproof construction allows the Monitoring Pen to be used for long-term, unattended monitoring of chlorophyll ﬂuorescence parameters in lab or feld experiments, even in challenging environmental conditions. It is battery operated (internal or external battery) and can be provided with an optional solar panel power supply.
The Monitoring Pen is capable of measuring Ft, QY, OJIP, NPQ, and has automated Light Curve protocols. Its is invaluable for studying photosynthetic activity, long-term monitoring of photosynthetic performance in naturally changing environmental conditions, stress detection, herbicide testing, and for monitoring growth performance in controlled environments and field conditions.
