OS5P+ Advanced Chlorophyll Fluorometer

The OS5P+ is a cutting-edge portable chlorophyll fluorometer designed for in-depth analysis of plant physiological processes and stress responses. Its robust field-portable design combined with advanced pulse-modulated technology allows researchers to precisely evaluate photosynthetic efficiency, stress responses, and photoprotection mechanisms in plants.

How it works

The OS5P+ uses pulse-modulated fluorescence to analyze chlorophyll fluorescence emission, accurately measuring parameters such as quantum yield, non-photochemical quenching (NPQ), electron transport rates (ETR), and comprehensive quenching analysis.

Its innovative internal actinic light source stabilizes white light output, ensuring consistent and precise measurements crucial for accurate stress evaluation.

Applications

  • Comprehensive plant stress analysis (drought, heat, cold, salinity, nutrient deficiencies)
  • Research on photoprotection mechanisms, including NPQ, chloroplast migration, and photoinhibition
  • Agricultural research and plant breeding
  • Environmental impact and ecological assessments

Key features

  • Advanced Pulse-Modulated Fluorescence:
    Delivers highly accurate fluorescence measurements to assess photosystem II (PSII) efficiency under diverse conditions.
  • Multi-Flash FM’ Correction (Loriaux 2013):
    Accurately corrects fluorescence measurements under high actinic light conditions, eliminating common errors and ensuring reliability.
  • Graphical Colour Touch Screen Interface:
    Intuitive and easy-to-navigate interface allows for quick setup and efficient data management.
  • Stable Internal White Actinic Light:
    Provides consistent illumination essential for reliable measurement of chloroplast migration and quenching parameters.
  • Automated Modulation Light Intensity Setup:
    Ensures correct setting of modulated light intensity, minimizing measurement errors and optimizing accuracy.
  • GPS Integration:
    Records precise location data alongside fluorescence measurements for enhanced spatial analysis.
  • Comprehensive Quenching Protocols:
    Includes Kramer lake model, Hendrickson lake model, and Puddle model parameters, enabling detailed study of photoprotective mechanisms and plant stress responses.
  • Innovative PAR Clip:
    Provides reliable PAR measurements and precise leaf temperature data, enhancing measurement accuracy and usability in the field.
