The DA-Meter - developed by Prof. Costa's team from the University of Bologna - is an instrument that, by means of its absorbency properties, allows to
measure the chlorophyll's content in a fruit. The content in chlorophyll in a fruit is a precise index of a fruit's ripening state.
Thus, the DA-Meter allows to know the ripeness state, and the way it works does not depend on the season’s weather conditions, a factor which influences other kinds of measurement
such as the brix index.
