CCM-200A plus Anthocyanin Content Meter

CCM-200A plusAnthocyanin Content MeterA hand-held device for the non-destructive determination of anthocyanin content in leaves andflowersNon-destructiveAccurate and reliableStorage of up to 160,000 data setsData averaging (2-30 samples)Graphic displayLightweight battery portableDesigned for rapid screeningAnthocyaninAnthocyanin is a red/purple flavonoid pigment found inphotosynthetic tissue, flowers and fruit. Its primaryfunctions are:Attracting pollinators“Sunscreen” against photoinhibition and high lightstressProtective camouflage against herbivoresAnthocyanin is found in high concentrations in manyberry related species.Research has suggested that anthocyanin may havepotential human health benefits in the restriction of thedevelopment of some cancers.References:Morris J.B., Wang M.L.

HortScience 40(3):685-686Non-destructive and battery portableThe CCM-200A plus is the world’s most advancedanthocyanin content meter providing fast, accurate andreliable determinations on intact plants.The battery portable CCM-200A plus providesanthocyanin content determinations in the field withoutthe need for destructive laboratory sampling. Specificallydesigned for fast field screening, each measurementtakes only 2-3 seconds to perform.Anthocyanin content is expressed in ACI (AnthocyaninContent Index) units.Data averagingData may be made as:Single measurements2-30 measurements averaged (with graphing)10-30 measurements averaged with applied sigma 2standard deviation to exclude rogue data points (withgraphing).

Large integral data storageUp to 160,000 anthocyanin content measurements canbe stored in the internal memory. There is norequirement for an external data logger, computer orfrequent returns to the laboratory to download data.Stored data can be reviewed, in the field, on the display.Once back in the laboratory, data is quickly and easilytransferred to a PC via USB or RS232. Measurementsmay be output individually by USB or as the completestorage file.Technical SpecificationsMeasured parameters: Optical absorbance in twodifferent wavebands: 530nm (Anthocyanin) and 931nm(Near Infra-Red) providing ACI valueMeasured area: 1cm diameter circleResolution: 0.1 ACI unitRepeatability: +/- 1 %Sampling acquisition time: 2-3 secondsSource: Custom 2 wavelength LED moduleDetectors: Two silicon photodiodes with integralamplifiers for absorbency measurements, powermonitoring and temperature compensationData modes: Single point, selectable 2-30 pointaverage and a statistical 10-30 point protocol thatdisregards data beyond a 2 sigma standard deviationStorage capacity: Up to 160,000 measurementsUser Interface:128 x 32 pixel graphic display, 8 keysfor measurements, data manipulation, beep signalstatus and warningsProven scientific principlesAnthocyanin has distinct optical absorbancecharacteristics that the CCM-200A plus exploits tonon-destructively measure relative anthocyaninconcentrations.By measuring the amount of energy absorbed in the530nm band an estimate of the amount of anthocyaninpresent in the tissue is possible. Absorbance in theinfrared band can be used to quantify and account forleaf thickness, so providing a more accurate ACI value.The CCM-200A plus employs new, precision LEDtechnology to further enhance measurement accuracyand repeatability.Output: USB 1.1 and RS232.
