CCM-300 Chlorophyll Content Meter
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.
- 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
| 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. |
