The patented technology used in the Dualex clip is based on chlorophyll fluorescence and on the screening properties of polyphenols contained in the plant leaf epidermis.

Their measurement is unaffected by the variable fluorescence and is independent of the chlorophyll concentration of the leaf.

This procedure is not destructive and is very quick and simple. It requires no calibration or adjustment of the light source. No preparation of the plant is required and the measurement can be taken outside, in the open field, or under ambient light.

Applications for Processed Foodstuffs
