    • How it works

    The ACM-200plus utilizes distinct optical absorbance characteristics of anthocyanin pigments, specifically measuring optical transmittance at two wavelengths (530 nm for anthocyanin and 931 nm for leaf thickness compensation).

    The meter calculates an Anthocyanin Content Index (ACI), offering a reliable, relative measurement that correlates well with traditional chemical assays.

    Applications

    • Plant and crop physiology studies
    • Leaf senescence monitoring
    • Agricultural breeding and production
    • Quality control in floriculture
    • Research and teaching in plant sciences
