PAR-FluorPen FP 100-MAX-LM
Includes an integrated Light Meter, one of the communication modules (Bluetooth, USB, or serial),
FluorPen 1.0 software, protocol update, and user's guide. Measures Ft, QY, NPQ, OJIP, Light Curve, and
Photosynthetically Active Radiation (PAR) in the range from 400 to 700 nm. Equipped with a standard
leaf-clip.
PAR-FluorPen FP 100-MAX-LM-D
Includes an integrated Light Meter, one of the communication modules (Bluetooth, USB, or serial),
FluorPen 1.0 software, protocol update, user's guide. Measures Ft, QY, NPQ, OJIP, Light Curve and
Photosynthetically Active Radiation (PAR) in the range from 400 to 700 nm. Adapted for use with
detachable leaf-clips; leaf clips sold separately.
FluorPen measures the following parameters:
Ft - Instantaneous Chlorophyll Fluorescence
Ft is equivalent to Fo if the leaf sample is dark-adapted.
QY - Quantum Yield
QY is a measure of the Photosystem II efficiency. In a dark-adapted leaf this is equivalent to Fv/Fm. In a
light-adapted leaf it is equivalent to Fv’/Fm’.
NPQ* - Non-Photochemical Quenching
The NPQ protocol is the most typically used measuring approach to quantify photochemical and non-
photochemical quenching. The measurement should be performed with a dark-adapted sample (see more
in Chapter 8.E. of this Manual).
