1. Measurement Principles and Characteristics
■ Measurement Principles
This device measures powder whiteness according to our own uniquely
developed standards. It measures reflectivity and utilizes two blue LEDs as its
light source. The light from the blue LEDs is passed through a diffuser panel and
shined onto the sample surface at 45 degree angles from both the left and right.
A photo diode measures the amount of reflected light. The whiter the sample, the
more light is reflected back and detected and thus a higher measurement value
is registered. The LEDs are a blue color with a 466nm center wavelength. They
are adjusted to provide a similar measurement that the previous model (C-100)
created when used with it’s blue filter. In addition to having a starch calibration
curve built in as the base calibration curve, a function allowing the user to set
their own calibration curves is also included, making it possible to measure the
whiteness of a variety of powders.
<Configuration Diagram>
■ Characteristics
The new C-130 model is smaller and more compact than our previous C-100
model. Furthermore, using blue LED light sources allow for a longer light source
lifetime reduced power consumption and reduced heat generation. In addition,
the required sample size has been greatly reduced. Using starch as an example,
about 13.5g of sample was required in the C-100. The C-130 only requires
approximately 5.5g of starch, Not only has ease of packing of the sample been
improved, but the amount of time spent preparing for the measurement has been
reduced. Finally, sensitivity calibration when the device is turned on has been
reduced, allowing measurements to begin must faster than with previous models.

method for starch. Different packing methods will
apply to samples with larger diameters, viscosity,
moisture, runny sample, etc.
(1) Heap the sample onto the sample platter.
(2) Use the spoon with spatula to pack down the sample.
(3) Use the spoon with spatula to level off the sample to the
height of the edge of the sample platter.
An accurate measurement cannot be taken if there
are cracks or lumps in the surface of the sample.
Use the spatula to make the surface as flat and
smooth as possible.
[Note] When the surface of the sample to be measured is
as flat as possible, the measurement will be very
[Note] If powder sticks to the outside or bottom of the
sample platter, clean it with the brush. Powder
stuck to the sample platter may cause it to tilt,
resulting in the measurement not being accurate.
While cleaning the sample platter, the spatula may
be used to hold down the sample and keep the
surface flat and smooth.
[Note] Depending on the sample, contact with the air may
cause drying or an increase in moisture content.
When handling such samples, it is necessary to
move quickly to the next operation after packing
down the sample.
[Note] If several samples are measuring at the same time,
Sample Platter Holder is useful in this purpose.

7. How to Make a User Calibration Curve
7-1.About user calibration curves
For users of previous models (C-100), measurement
values compared to those of previous models may be
different when measuring samples other than starch.
Additionally, there may be a need for a different
calibration curve than the factory standard provided,
depending on the measurement requirements (e.g.,
customer internal standards).
In such cases, it is possible to calculate the reading by
creating a user calibration curve.
[Note] You can register up to 9 user calibrations from
[02] to [10].

[Note] At least two samples should be used when
creating a calibration curve. If less than five
samples are used, repeat the largest value
for the remaining items. As an example, when
three samples are used, sample three values
should be repeated for sample four and five in
both columns.
