Overview
JINGKELIAN WSB-2Y digital display whiteness meter is a Benchtop digital display fluorescence whiteness meter with a Measurement range of 0~ 199. The instrument is composed of Illuminant, Optical inspection system, detection system, data processing and display system, etc. The overall whiteness is R457, of which R457 = blue light whiteness r457 + fluorescence whiteness F. The instrument is designed in strict accordance with the Standard light source and illumination conditions stipulated by the International Commission on Illumination (CIE), defining the ideal surface whiteness of Light spectrum diffuse reflection ratio of 1 is 100, and the absolute black surface whiteness of Light spectrum diffuse reflection ratio of zero is 0.
Features
1. Large-screen high-definition LCD liquid crystal display, clear and comfortable reading, not affected by natural light
2. Low drift High Accuracy Integrated Circuit, Illuminant Effective Long Life, Ensure Long Stable Operation of Instrument
3. Standard value transmitted by National Calibration Whiteboard, accurate and reliable measurement
4. Reasonable and concise design of light path ensures correctness and Repeatability of Measured value
5. Simple operation, accurate measurement of paper Opacity
Principle
The WSB-2Y digital whiteness meter uses the principle of photoelectric conversion and adopts the analog-to-digital conversion circuit to measure the radiant luminance energy value of the white reflection on the surface of the sample. After signal amplification, A/D conversion and data processing, the corresponding whiteness value is finally displayed.
Applications
Chemical building materials, paper Cardboard, plastic products, white cement, paints Coatings, ceramics, Spinning & weaving printing and dyeing, enamel, porcelain clay, flour, salt, tale powder, starch, detergent, cosmetics and other objects whiteness measurement
