Product Description

The OS1-FL incorporates all components necessary for rapid, field screening of large number of samples.

Instrument operation is intuitive with all control settings made, and tests conducted via a simple array of dedicated control keys. Automatic test modes for both Fv/Fm and Yield measurements control precise cycling of optical sources and data acquisition, under control of user-defined parameter settings. The user can easily conduct tests, triggering repetitive operation and logging results, using a single button.

Chlorophyll fluorescence is a powerful analytical tool that allows non-destructive study of the photosynthetic apparatus. It is the premier research technique for monitoring health and condition in Plants, Crops, and Algae. Because the technique is so versatile and studies can be performed in the field, it has become an integral part in many areas of research from agriculture and crop production to plant physiology and forestry chlorophyll fluorescence has proven to be an amazing and reliable research tool.

Now it is easier than ever to Detect and Monitor the effects of environmental stress (drought, disease, root pathogens, heat, herbicide, etc.), identify desirable traits to improve Plant Breeding programs (i.e. resistance to stressors), and verify plant/crop performance in Ag-Chem development.

Opti-Sciences line of Chlorophyll Fluorometers are superb for field and lab work and even teaching. All of our units are field portable, lightweight, self contained, and provide and expansive range of tests.

There is a model for every level of user and for every budget.

The OS1-FL features internal modulated excitation and high-intensity saturation sources as well as sensitive detection electronics and extensive data logging capability. Dedicated test modes enable the rapid measurement of dark-adapted (Fv/Fm) and steady state (Y) parameters without the typical complicated instrument setup. Conditions at the leaf surface (illumination and temperature) can be logged with the optional PAR leaf clip.
