Color Reader
CR-20
|
|
|
|
The handheld CR-20
(combined successor to the CR-11, CR-13, CR-14), color reader, measures
|
|
the color and
whiteness of foods or raw materials in paste, solid, or powder form. It
boasts an
|
|
impressive LCD screen that
displays measurement results from one of eight color spaces/
|
|
colorimetric indexes
including L*a*b*, L*C*h, Yxy, Munsell,
WI (CIE/ASTM E 313-96), Tint
|
|
(CIE/ASTM E 313-96), YI
(ASTM E 313-96).
|
|
|
|
|
|
This
instrument can be utilized in order to control color from raw materials
through the process of
|
|
|
manufacturing.
It can also quantify the effect that storage has inflicted on the whiteness
of a
|
|
|
product
during transportation. The CR-20 fits comfortably in the palm of your hand.
It is both
|
|
|
battery-operated
and light-weight, so it is extremely portable. This unit can also be
connected to
|
|
|
an
AC adapter for external power.
|
|
|
|
|
|
This device
is affordable and easy-to-use. It is particularly ideal for industries that
are just beginning
|
|
|
to
measure color or need multiple devices that are reliable yet affordable. The
functionality of this
|
|
|
instrument
is user-friendly and does not perform any unneeded processes. This makes
things simple.
|
|
|
There are 3
easy steps to operate the CR-20, switch on power, perform white calibration,
and measure
|
|
|
the
sample. All color measurements are taken using conditions of the standard illuminant D65 and
|
|
|
10 degrees
observer while offering a Xenon lamp light source for longer life and more
stable readings.
|
|
|
|
|
|
The CR-20
color reader has a protective glass cap. This allows direct measurement of
pastes, powders,
|
|
|
or
wet objects without needing to fill a cell. This device is printer-ready with
USB connectivity in case
|
|
|
you
need a hard copy of your results. With built in software the CR-20 will allow
you to make multiple
|
|
|
measurement
and average them with one touch averaging button, perfect for uneven color
objects.
