Product Code : Apan-WM-206
Product Description

As an authorized dealer we are offering wide gamut of "Colour Appearance" test and measurement instruments for wide range of aplication.

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.



  •  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.
  • Optional - Powder Forming Apparatus
  • Optional - RS-232 data output to connect 
  • Optional - Bluetooth data output.
