CCM-300 Chlorophyll Content Meter

The CCM-300 Chlorophyll Content Meter is a handheld device designed specifically to measure chlorophyll content using a fluorescence ratio technique pioneered by Gitelson et al. (1999).

Ideal for small, thick, curved, or otherwise difficult-to-measure samples, the CCM-300 reliably assesses chlorophyll concentration across a broad range, offering precise data for researchers, agronomists, and environmental scientists.

    • How it works

    The CCM-300 employs the chlorophyll fluorescence ratio (CFR) method, measuring the emission ratio of red chlorophyll fluorescence from 700-710 nm to far-red fluorescence from 730-740 nm.

    This fluorescence-based approach surpasses traditional absorption techniques, providing accurate readings even with samples that do not fully cover the measuring aperture. This method ensures high reliability and correlation with chemical assays, especially at elevated chlorophyll levels.

    Key Features
