Description
Mode of function
The chlorophyll concentration in leaves is measured using
the N-Tester. The mean of 30 individual measurements is
displayed after successful application. The youngest fully
developed leaf is illuminated in two wavelength ranges
using light that is absorbed in different intensities by the
chlorophyll. The remaining transmitted light is captured in a
photodiode and converted to a measuring value.
A minimum of 30 individual measurements is required to
provide a representative reading. Individual values that
deviate considerably (faulty measurements) are not
considered.
