Overview

The FMS 1 chlorophyll fluorescence measurement system is a
versatile pulse modulated fluorimeter, designed to measure
chlorophyll fluorescence emission from a wide range of different
sample types engaged in photosynthesis under ambient light
conditions.
The FMS 1 chlorophyll fluorometer consists of a control unit
housing all of the electronics, optics and light sources necessary to
derive most common chlorophyll fluorescence parameters. These
are optically linked to the sample by a statistically randomised
fibre optic cable that is suitable for insertion into a range of sample
containers such as oxygen electrodes, gas analysis chambers, petri
dishes and microtitre plates.
The system may be operated in several different modes: serial
connection to a Windows® PC enables real-time instrument control
and data presentation.
Captured data is simultaneously presented as a real-time
chart recorder emulation and parameters-only format for easy
identification of key experimental events. This PC mode of operation
is suitable for development of complex protocols which may be
programmed into the instrument using the simple drag and drop
editor to generate user-defined scripts. These scripts automate the
execution of experiments in the field, allowing complex protocols involving many control events to be operated with the same ease
as single control event measurement such as Fv/Fm.
Once programmed, the FMS 1 chlorophyll fluorometer can be
operated as a stand-alone fluorimeter inside the laboratory
or outside (via connection to an optional external battery). All
measurement data and calculated parameters are saved to integral
protected memory. The unit can store up to six experimental
protocols, any one of which may be accessed and executed using
the built-in menu system. When data collection is complete the
results can be downloaded to the Windows® software for full
analysis.
All of the light sources required for modulated measurement of
common fluorescence parameters are self-contained within the
instrument.
• 594 nm amber modulating beam with 4 step frequency
control (optional 470 nm blue LED).
• Dual-purpose halogen light source providing actinic light
(0 - 3000 µmol m-2 s-1 in 50 steps) and saturating pulse (0
- 20,000 µmol m-2 s-1 in 100 steps).
• 735 nm far-red LED source for preferential PSI excitation
allowing accurate determination of the Fo’ parameter.
