The PAR-FluorPen FP 100-MAX-LM includes all features of the FluorPen FP 100-MAX, - it measures chlorophyll fluorescence parameters Ft, QY, NPQ, OJIP, and Light Curve (QY).
In addition, 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 within the 400-700 nm waveband. Instant readouts are provided as average values of 20 measurements.
The Sample holder is a clip for gentle fixing of a leaf sample and its short duration dark adaptation. “D” version of the PAR-FluorPen with detachable leaf-clips is suitable for experiments where long term dark adaptation is needed.
Measured data are sequentially stored in the internal PAR-FluorPen memory. Data transfer to a PC is via USB or Bluetooth communication. Comprehensive FluorPen software provides data transfer routines and many additional features for data presentation in tables and graphs.

Several types of leaf-clip are available:
Standard leaf-clip: suitable for experiments where short term dark adaptation is needed.
Open leaf-clip: suitable for measurements in ambient light (experiments where no dark adaptation is required).
Customised sample holders: for instance, for mosses, lichens and other experimental material.
Detachable leaf-clips: suitable for experiments where long term dark adaptation is needed. They also allow simultaneous dark-adaptation of several leaves using several clips in situ under light, and then doing the readings one after another by attaching the device unit to each clip.
Recalibration of the PAR Sensor
Recalibration of the PAR sensor in the PAR-FluorPen device – recommended after 2 years of use.
Replacement USB Communication Cable
Replacement USB cable allowing connection between the “pen” devices and a PC (the device is delivered with one USB cable, which is included in the device price).
Supplementary detachable leaf-clips for use with the PAR-FluorPen FP 100-MAX-LM-D. 10-piece set.
