Introduction: Benchtop whiteness tester is mainly applied to the whiteness measurement of non-color surface smooth objects or powder, can accurately get the brightness value consistent with the visual sensitivity. Fluorescent whitening agent for the treatment of the object, you can quantitatively reflect the whiteness value after fluorescence enhancement. Can be widely used in textile printing and dyeing, paint, chemical building materials, paperboard, plastic products, white cement, ceramics, enamels, talc, starch, flour, salt, detergents, cosmetics and other substances whiteness measurement. The instrument overall by the light source, optical system, detection system, data processing and display system, etc., the overall whiteness R457. R457 = blue whiteness r457 + fluorescent whiteness F. An ideal surface with a spectral diffuse-to-anti-strike ratio of 1 is defined to have a whiteness of 100 and an absolute black surface with a zero diffuse reflectance of zero. The instrument is designed in strict accordance with the standard light source and test conditions stipulated by the International Commission on Illumination (CIE). It has passed rigorous testing, commissioning and implementation of the enterprise standard Q / TDKY02-2004, applicable to GB2913, GB5950, GB8940.1, GB12097 , GB13025.2 and other national standards. Technical Parameters: Measuring range: 0 ~ 199 Measurement content: Blu-ray brightness r457, fluorescence whitening F Light source: LED light source Test conditions: in line with GB / T3978 45/0 Display: LCD liquid crystal display Measuring aperture: ¢ 30 Minimum indication: 0.1 Measurement repeatability: 0.2 Indication error: ≤ ± 1 Use of the environment: temperature (5 ℃ ~ 35 ℃); humidity (≤ 85% RH) Transport, storage environment: temperature (-20 ℃ ~ 50 ℃); humidity (≤ 90% RH) Power supply: AC 220V / 50Hz.
