Rather interesting test of the accuracy and efficiency of these devices. I wrote
here about the importance of getting consistent and comparative data, this could well be another tool to add to the list.

Chlorophyll Content Index as measured by the Opti-Sciences CCM-200 was found to correlate positively with 90% acetone extracted Chl a content in three species of intertidal wetland plants, including one grass (Fam. Poacae), one rush (Fam. Juncaceae) and one tree (Fam. Rhizophoraceae). The strength of the correlation varied by species, with J. roemerianus < S. alterniflora < R. mangle (Table 2). The two species with flat leaves (S. alterniflora and R. mangle) showed better correlation between the CCI and Chl a content, presumably because a flat leaf is better at reflecting and transmitting the LED light to the detector in the CCM-200.
