Detail OPTI-SCIENCES CCM-300
Measured Parameters : CFR or Chlorophyll Fluorescence Ratio - fluorescence emission ratio of intensity at
735nm / 700nm, or readout or relative chlorophyll content
-2 in mg/ m .
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/ m¯ ² .
Repeatability : is 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 : ( 1) LED 460 nm blue diode half band width 15 nm.
Detector : Two solid state, high sensitivity detectors. Band
limiting filter sets provided. Dual wavelength detection at
the same time. 700nn to 710nm, and 730 nm to 740 nm.
Detection : Modulated light digitally controlled to minimize
background detection. Temperature compensation included
for light source and detector
Storage Capacity : Up to 2 gigabytes of non-volatile flash memory
Modes : single point measurement, measurement averaging
for 2- 30 samples, averaging with 2 sigma outlier removal,
or median determination.
Sample interface : fiberoptic probe 4mm in diameter
