Screening
The most affordable modulated fluorometer for use with dark clips!
FV/FM meter allows reliable measurements of FV/FM, FO, and FM
FV/FM is considered the gold standard of chlorophyll fluorescence measurement because it allows sample comparison at the same known common dark adaption state and measurements generally correlate to photosynthesis measurement. While healthy values vary by species between 0.79 to 0.84, lower FV/FM values indicate plant stress is affecting Photosystem II.

The FV/FM meter is most affordable modulated fluorometer for use with dark clips. FV/FM is the most used chlorophyll fluorescence measuring protocol in the world because it allows comparison of samples in the same known dark-adapted state. This allows comparison of samples where the light is changing. Samples can be compared under canopy or in situations where steady state photosynthesis is hard to measure. The FV/FM meter has an optical probe that permits measurement with dark adaptation clips, allowing fast measurement of large plant populations.

Articulated locking arm
This is a tripod like accessory that allow PAR clips, The Y(II) meter, or the iFL measuring chamber to be adjusted and locked at various locations, and angles for laboratory measurement. Angles and locations can be quickly set and locked in position with a single adjustment knob.
Instrumentation not included.
Dark adaptation clip
Dark adaption clips are designed to provide an affordable yet reliable measuring solution for large populations of plants. Some Scientists buy hundreds of dark clips. The clips are built with sturdy and weather resistant yet cost effective materials. Flexible gaskets automatically seal the sample area from any light. An easy to operate slider is built-in to expose the sample surface after dark adapting.
