FluorPen FP 100

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.

Measured data are sequentially stored in the internal 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.

FluorPen FP-100 Features
The basic model records two parameters:

  • 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 dark-adapted samples and to FV ‘ /FM ‘ in light-adapted samples.

FluorPen FP 100-MAX model includes additional pre-defined protocols for measuring:

  • OJIP Analysis
  • Application of chlorophyll fluorescence fast-transient analysis (OJIP) is a simple and non-invasive tool to monitor chloroplast function. Provided OJIP analysis is used as sensitive and reliable fast test for the functionality and vitality of photosynthetic system.
  • NPQ – Non-Photochemical Quenching
  • Provided are two predefined NPQ protocols differing in the duration of light exposure and dark recovery phase as well as in the number of intervals between the pulses. It is typically used for quantification of photochemical and non-photochemical quenching in dark-adapted samples.
  • Light Curve
  • There are three predefined Light Curve protocols based on pulse modulated fluorometry differing in number and duration of single light phases and light intensities. Light Curve protocols provide successive measurements of the sample photosynthesis under various light intensities of continuous illumination relating the rate of photosynthesis to photon flux density.
