CCM-300 Chlorophyll Content Meter

Soil & CropsPhotosysnthesis Chlorophyll & Respiration

The CCM-300 uses a proven fluorescence ratio technique for chlorophyll content measurement at an affordable price. Readout is directly in chlorophyll content mg/m2, and measurement ratio.

Quantity

Overview

Reliable results on very small leaves, stems, petioles, and immature plants
Chlorophyll content can now be measured from germination through maturity on most plants
High degree of correlation with chemical tests, even at higher chlorophyll content levels.
Larger measuring range - reliable measurement from 41 mg/m2 to 675 mg/m2
Great for nitrogen management applications because it does a better job with well fertilized plants, used as a reference, in management applications.
Allows onboard averaging of up to 30 measurements for nitrogen management applications
USB port - data files open directly into Excel ®
2 Gigbytes of memory

Specification

Measured Parameters	CFR or Chlorophyll Fluorescence Ratio - fluorescence emission ratio of intensity at 735 nm / 700 nm, or readout or relative chlorophyll content in mg/m2.
Measurement Area	3 mm diameter circle, external diameter of 4 mm. However, the instrument will reliably measure samples that are much smaller than 3 mm.
Resolution	Ratio 0.01 or 1 mg/m2.
Repeatability	Dependent on signal strength. For samples with low signal strength, averaging of multiple measurements is recommended. For samples with good signal strength, ratio values of +- 0.03 or better, are common.
Noise	<+/- 2%.
Source	460 nm blue LED with half bandwidth of 15 nm.
Detector	Two solid state, high sensitivity detectors. Band limiting filter sets provided. Dual wavelength detection at the same time. 700 nn to 710 nm, and 730 nm to 740 nm
Detection	Modulated light digitally controlled to minimize background detection. Temperature compensation included for light source and detector.
Modes	Single point measurement. Measurement averaging for 2-30 samples. Averaging with 2 sigma outlier removal. Median determination.
