NEW. A compact and affordable solution to Yield Y(II) measurements.

This compact and light-weight modulated fluorometer follows proven and established scientific principles to provide accurate measurements of the quantum yield of PS(II).
This tiny, hand-held meter also measures absorptance to provide the most accurate ETR values possible.

The Y(II) meter follows the advanced protocols determined by Loriaux (2006) to determine the maximum theoretical level of Fm’ with an infinitely intense saturating pulse.
Thousands of datasets can be stored in the 2Gb of on-board memory and a high speed USB is provided to download readings to a computer.
