The CFM-3 Chlorophyll Fluorescence Module

PP Systems - CIRAS-3 Portable Photosynthesis System The CFM-3 Chlorophyll Fluorescence Module is capable of both independent measurement of chlorophyll fluorescence as well as simultaneous measurement of photosynthesis and chlorophyll fluorescence.

The CFM-3 is compact and elegantly designed with all light sources and fluorescence detection capability built directly into the light unit. The CFM-3 can be used as an actinic light source for leaf gas exchange and as a pulse-amplitude-modulated (PAM) fluorimeter for measurement of chlorophyll fluorescence on both dark and light adapted vegetation.

The CFM-3 is capable of delivering saturating pulses up to 10,000 µmol m^-2 s^-1 which is extremely useful in accommodating a wider range of ambient light conditions. The CIRAS-3’s Multi-Pulse™ technology produces a sequence of saturating light levels for estimation of apparent Fm‘.

The CFM-3 Chlorophyll Fluorescence Module is an optional accessory designed exclusively for use with the PLC3 Universal Leaf Cuvette.
