 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 Brighttness 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 diplay.
