PAR-FluorPen FP 110-LM/S and PAR-FluorPen FP 110-LM/D include all features of the FluorPen FP 100-MAX, i.e., they measure chlorophyll fluorescence parameters Ft, QY, NPQ, OJIP, and Light Curve (QY). They feature an integrated GPS Module.
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 within the 400-700 nm waveband. Instant readouts are provided as average values of 20 measurements.
PAR-FluorPen FP 110-LM/S
Handheld fluorometer with integrated Light Meter, GPS module, USB/Bluetooth communication and dedicated software.. Measured parameters: PAR, Ft, QY, OJIP, NPQ, LC. The “S“ version uses firmly attached leaf-clip.
PAR-FluorPen FP 110-LM/D
Handheld fluorometer with integrated Light Meter, GPS module, USB/Bluetooth communication and dedicated software.. Measured parameters: PAR, Ft, QY, OJIP, NPQ, LC. The “D“ version is intended for use with detachable leaf-clips (clips are sold separately).
PAR-FluorPen FP 110-LM/X
Handheld fluorometer with integrated Light Meter, GPS module, USB/Bluetooth communication and dedicated software. Measured parameters: PAR, Ft, QY, OJIP, NPQ, LC. The “X“ version is mounted with custom-made leaf-clip.
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).
