Chlorophyll Content Meter - works on small & difficult samples & provides a larger reliable measuring range than other instruments
The CCM-300 uses a proven fluorescence ratio technique for chlorophyll content measurement at an affordable price. Readout is directly in chlorophyll content mg/m2, and measurement ratio.
CCM-300 Chlorophyll Content Meter is designed to measure difficult samples. It can be used on conifers, turf grasses, moss, lichen, immature wheat, immature Arabidosis, stems, and petioles, as well as easier samples, like corn and broadleaf plants. The instrument was designed around research done by Gittelson, Bushman, & Lichtenthaler in 1999. The research shows that this method offers a larger reliable measuring range than absorption. style meters, provides a ratio that correlates with chemical tests & provides direct readout of chlorophyll content in mg/m2, that is reliable for many plant species. Adjustments to the direct chlorophyll content readout equation are possible for other species.
CFR or Chlorophyll Fluorescence Ratio - fluorescence emission ratio of intensity at 735 nm / 700 nm, or readout or relative chlorophyll content in mg/m2.
3 mm diameter circle, external diameter of 4 mm. However, the instrument will reliably measure samples that are much smaller than 3 mm.
Ratio 0.01 or 1 mg/m2.
Dependent on signal strength. For samples with low signal strength, averaging of multiple measurements is recommended. For samples with good signal strength, ratio values of +- 0.03 or better, are common.
