Whiteness meter External Probe
Application:

Whiteness Meter is mainly used to directly measure the
whiteness value of object or powder with flat surface.
Can be widely used in whiteness measurement of textile
printing and dyeing, paint, chemical building materials,
paper board, plastic products, white cement, ceramics,
enamel, talc powder, starch, flour, salt, detergent,
cosmetics and other substances.

Principle
The instrument consists of Light Source, Optical System, Detection System, Data Process and Display System. The
Whiteness Calculation Formula of the instrument is blue light whiteness R457.
The light source of the instrument is long-life LED with 457nm, conforming to the light source requirement in the JJG
512-2002 National Metrological Whiteness Meter Verification Regulation. The measurement of the instrument adopts
the principle of photoelectric effect. The diffuse reflectance Radiant Brightness Energy Value of the sample surface is
receive by the optical cell. Then, the value is amplified by high-precision auto zeroing operation amplifier, inputted to
the calibration circuit for energy calibration. Then, the whiteness value of the sample is directly shown on the display.


Features
* The optical path design is reasonable, simple. Adopt
filter system with correction, the whiteness can be
reflected quantitatively.
* Use of high quality imported components.
* No preheating after starting, measurements can be
taken after simple calibration, easy to operate.
* Able to memory 254 groups of measurement data.
* Pass strict inspection and testing, the instrument
conforms to the JJG 512-2002 Whiteness Meter
Verification Regulation. Also conforms to GB3978,
GB3979, GB7973, GB7974, ISO2470, GB8904.2,
QB1840, GB2913, GB13025.2, GB1543, ISO2471,
GB10339, GB5950, GB12911 and other standards.
* Use RS-232 data output to connect with PC.
* Provide Bluetooth data output choice.
