Home » OS5-FL Chlorophyll Fluorometer

OS5-FL Chlorophyll Fluorometer Pulse Modulated Field Portable

The OS5-FL incorporates all components necessary for extensive research, integrated by a straightforward user-friendly control system. On board viewing and storage utilities facilitate in field verification, rapid management, and export of data. The OS5-FL measures light and dark adapted parameters such as: Fo, Fm, Fv/Fm, Y, Ft, Foq, Fms and is also capable of calculating photochemical and non-photochemical quenching coefficients qP, qN, and NPQ. Accessory inputs allow for additional parameters such as PAR.

Product Description

Chlorophyll Fluorescence is a simple non-destructive method used to determine health, performance, and status in whole plants and algae. Opti-Sciences Chlorophyll Fluorometers are ideal for research and bio-remediation studies, along with plant breeding, production, and improvement programs. The OS5-FL provides the essential analytical data to enhance plant performance, increase yield, monitor and maintain optimal growth conditions, prevent irreversible crop damage, and study the effects of specific environmental stressors.


The OS5-FL Modulated Chlorophyll Fluorometer from Opti-Sciences is the most technically advanced portable chlorophyll fluorometer on the market. Lightweight, battery operated and completely self-contained, the ease of use and pick-up-and-go-portability is surpassed only by the expansive range of test parameters and data gathering capabilities of the OS5-FL.
