The CL-01 Chlorophyll content meter provides a convenient, low cost method of measuring the relative chlorophyll content of a leaf sample. The measurement of chlorophyll content provides an indicator of photosynthetic activity relating to the nitrogen concentration of the sample. This is particularly significant in plant growth programs where affects of the addition of nitrogen to a crop may be closely monitored.
The field-portable, hand-held device determines relative chlorophyll content using dual wavelength optical absorbance (620 and 940nm wavelength) measurements from leaf samples. Relative chlorophyll content is displayed in the range 0 – 2000 units.
