A hand-held device for the non-destructive determination of anthocyanin content in leaves and flowers Non-destructive and battery portable The CCM-200A plus is the world's most advanced anthocyanin content meter providing fast, accurate and reliable determinations on intact plants. The battery portable CCM-200A plus provides anthocyanin content determinations in the field without the need for destructive laboratory sampling. Specifically designed for fast field screening, each measurement takes only 2-3 seconds to perform. Anthocyanin content is expressed in ACI (Anthocyanin Content Index) units. Data averaging
Data may be made as:

 Single measurements
 2-30 measurements averaged (with graphing)
 10-30 measurements averaged with applied sigma 2 standard deviation to exclude rogue data points (with graphing).
