2. General Information
FluorPen
is a portable, battery-powered fluorometer that enables quick and precise measurement of
chlorophyll fluorescence parameters in the laboratory, greenhouse, or in the field. It can be effectively
used for studying photosynthetic activity, stress detection, herbicide testing, or mutant screening.
Affordable price and straight-forward two-button operation makes the FluorPen a perfect tool for
teaching photosynthesis. Because of its rapid measurement capability and large internal memory, the
FluorPen is also an invaluable tool for large plant-screening programs.
PAR-FluorPen FP 100-MAX-LM includes all features of the FluorPen FP 100-MAX, i.e., it measures
chlorophyll fluorescence parameters Ft, QY, NPQ, OJIP, and Light Curve (QY).
Besides that, the PAR-FluorPen incorporates an integrated Light Meter for direct digital readouts of
Photosynthetically Active Radiation (PAR) in the range from 400 to 700 nm, the span in which plants use
energy during photosynthesis. PAR is measured as Photosynthetic Photon Flux Density (PPFD), which is
indicated by units of quanta (photons) per unit time per unit surface area. The sensor has a uniform
response to photons withing the 400-700 nm waveband. Instant readouts are provided as average values
of 20 measurements.
Measured data are sequentially stored in the internal FluorPen or PAR-FluorPen memory. Data transfer to
a PC is via USB or Bluetooth communication. Comprehensive FluorPen 1.0 software provides data transfer
routines and many additional features for data presentation in tables and graphs.
