| The Satake NCG1A Flour Colour Grader is a
high resolution visible-band spectrophotometer. This grader uses the
TRISTIMULUS principle to give colour in terms of the L* a*b* values.
For convenience the sample is
normally presented
DRY giving fast readings (3seconds).
Also for legacy comparisons the unit
has been fitted with the handy Kent Jones Colour Grade calibration reading
- as derived from the L* a*b* results.
This Colour Grade reading is a quick check system with a typical accuracy
of 0.5 kj units for wet sample presentation - once set to customer
reference values. Dry sample can however be used also with a with a
slightly lower accuracy.
However sample
should be presented using the traditional wet paste
method in this case for ultimate colour grade linearity.
Ash as a function of colour can
also be
displayed.
As a general
purpose colour meter the NCG1A can be used on other cereal products, and
also carries calibrations for general colour measurment outside of the
cereal uses.
The data processing and control of the NCG1A
software is operated by a PC* running under Windows XP/Vista**. The NCG1A is easy to operate
and is very user friendly.
