Introduction
The CCM-300 Chlorophyll Content Meter is a modulated fluorometer that uses the emission ratio of red
chlorophyll fluorescence at 700nm to the far red emission fluorescence value at 735nm., utilizing a fiber
optic probe. The source and detector wavelengths were selected from the Science developed by Gitelson
A. A., Buschmann C., Lichtenthaler H. K. (1999) “The Chlorophyll Fluorescence Ratio F735/F700 as an
Accurate Measure of Chlorophyll Content in Plants” Remote Sens. Enviro. 69:296-302 (1999). It is a
handheld, battery powered device with almost unlimited built in data storage.
The instrument is powered by 2 AA batteries. NiMH or alkaline types may be used. Two sets of NiMH
batteries and a NiMH charger are included with the unit. The unit will typically run for 8-10 hrs on a
freshly charged set of NiMH batteries. Ambient temperature and battery charge will affect runtime.
The unit has a 320x480 pixel display with touch sensitive screen. While finger touch may be used
successfully for most functions, A stylus is provided for easier use of some of the input and control
buttons, such as entering file names.
