- Great for detecting stress causing agents that effect photosystem PSII.
- The OS1-FL provides direct readout of FV/Fm, Fm, and Fo, as well as Yield (or ?F/Fm?), Fs(or F), Fms (or Fm?)
- The most used, and most robust stress measurement parameters.
- Both PAR and leaf temperature measurements are possible as well with the Optional OS1-FL Par Clip.
- Flexible fiberoptic probe allows greater measurement flexibility.
- Up to 4,000 measurements can be stored on the OS1-FL and may be transferred with its built in computer interface for spreadsheet analysis, graphing, or storage.
