PAR-FluorPen FP 100-MAX-LM

PAR-FluorPen FP 100-MAX-LM includes all features of the FluorPen FP 100-MAX, i.e., it measures 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.

  • PAR - Photosynthetically Active Radiation measured as Photosynthetic Photon Flux Density (PPFD).
  • FT - Continuous fluorescence yield in non-actinic light. FTis equivalent to F0 if the leaf sample is dark-adapted.
  • QY - Photosystem II Quantum Yield. QY is equivalent to FV/FM in the dark-adapted samples and to FV ' /FM ' in the light-adapted samples.
  • OJIP - Chlorophyll Fluorescence Induction Kinetics.
  • NPQ - Non-Photochemical Quenching.
  • Light Curve (QY) - Photosystem II Quantum Yield estimated from fluorescence that is measured sequentially in several different light levels.
