DUALEX

DUALEX is a leafclip meter that  accurately measures chlorophyll  content (µg/cm²) and provides  indices for flavonols. DUALEX is extensively used in plant sciences for research on plant  responses to environmental stressors, nutrient management,  and physiological studies. DUALEX also calculates the NBI (Nitrogen Balance Index) which has  been proven to correlate best with  leaf nitrogen status.
