Luke is planning to procure a portable photosynthesis system for research purposes to be used in field conditions in Jokioinen Finland in 2026 and in Suonenjoki, Finland, in 2027. The system to be purchased will be used to measure photosynthesis in field and greenhouse crops. The system must be suitable for measuring plants with different types and sizes of leaves (and needles). Because of the usage in field conditions, the system must have a long battery life. For research purposes, the accuracy of measurements is essential. The system must also have an interface for saving and transferring data to external storage.

The procurement includes optional chambers that may be acquired within the limits of the allocated budget.
