Monitoring Pen
Quick, reliable and easy measurements in the field or laboratory
About...

PSI's Monitoring Pen is a lightweight, portable and durable fluorometer. It is an extended version of the popular FluorPen. Its robust and weatherproof construction allows the Monitoring Pen to be used for long-term, unattended monitoring of chlorophyll fluorescence parameters in lab or feld experiments, even in challenging environmental conditions. It is battery operated (internal or external battery) and can be provided with an optional solar panel power supply.

The Monitoring Pen is capable of measuring Ft, QY, OJIP, NPQ, and has automated Light Curve protocols. Its is invaluable for studying photosynthetic activity, long-term monitoring of photosynthetic performance in naturally changing environmental conditions, stress detection, herbicide testing, and for monitoring growth performance in controlled environments and field conditions.

Key Features

  • Rugged and compact device constructed for unattended extreme outdoor conditions
  • Autonomous operation and data storing
  • Up to 365-days of battery-powered operation (optional solution)


  • Pre-programmed protocols for common fluorescence parameters (Ft, QY, OJIP, NPQ) and for Light Curves
  • Online data acquisition (optional solution)
  • Sophisticated FluorPen software for data transfer routines and further processing

Monitoring Pen

MonitoringPen is a lightweight, portable and durable durable fluorometer. It is an extended version of the popular FluorPen. Due to its robust and weatherproof construction the Monitoring Pen is designed for long-term, unattended monitoring of chlorophyll fluorescence parameters in lab or feld experiments, even in rough environmental conditions. It is battery operated (internal or external battery) and it may optionally use a solar panel as a power supply.

Monitoring Pen is capable of measuring five most frequently used fluorescence parameters: Ft, QY, OJIP, NPQ, and Light Curve. Thus it can be effectively used for studying photosynthetic activity, long-term monitoring of photosynthetic performance in naturally changing environmental conditions, stress detection, herbicide testing, or growth performance monitoring in controlled and feld conditions.

Monitoring Pen features programmable autonomous operation with automated switch ON function, which allows long lasting and self-governing battery-powered operation. Measured data are sequentially stored in the internal 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.

Additionally, numerous monitoring units can be linked together and operated from the central steering unit, which is linked to a data logger and mobile modem for online data transfer (optional).


APPLICATIONS


  • Photosynthetic performance monitoring
  • Long-term environmental monitoring
  • Plant screening & field studies
  • Stress physiology
  • Agriculture & forestry
  • Oceanography: coral health

MONITORING PEN MEASURE


  • Ft - continuous fluorescence yield in non-actinic light. FT is 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 F’V/F’M 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

SOFTWARE


  • FluorPen software ( Windows 7, or higher compatible)
  • Real-time and remote control functions
  • Bluetooth and USB communication
  • Visualization and data transfer routines to Microsoft Excel (optional)
  • GPS mapping

Versions

Monitoring Pen MP 110-E

Durable, battery-powered fluorometer intended for autonomous use in feld conditions. It features
a waterproof metal case, measuring probe, thread for tripod attachment, external pack with batteries and the FluorPen 1.0 software for data collection and processing. Final confguration (working outdoor conditions, request for data logger, requirements for battery life, etc.) must be consulted prior to order.


Monitoring Pen MP 110-A

Submersible, battery-powered fluorometer intended for underwater measuring of fluorescence parameters (also autonomous). It features a waterproof case, measuring probe, and the FluorPen 1.0 software for data collection and processing. External battery pack with batteries is sold separately. Final configuration (working outdoor conditions, water depth, frequency of measurements, requirements for battery life, etc.) should be consulted with PSI prior to order.

Generally, version A is intended for maximum water depth up to 2 meters. The device is equipped with two buttons that alow direct control of the device (even under water). Version B can be used in deeper water (maximum 10 m). There are no buttons on the device. This version is intended for automatic measuring; the device control is enabled via commands preprogrammed in a PC (placed on shore). The device is usually fixed in static position under water.
