Brief introduction:
The paper digital display whiteness meter is mainly used to measure the whiteness of objects or powders with flat surface, which can accurately obtain the whiteness value consistent with the visual sensitivity. For the object treated by fluorescent brightener, the whiteness value after fluorescent brightening can be quantitatively reflected.

WSB- two   Paper digital whiteness meter
Paper digital whiteness meter Application and scope of application:

The paper digital display whiteness meter is mainly used to measure the whiteness of objects or powders with flat surface, which can accurately obtain the whiteness value consistent with the visual sensitivity. For the object treated by fluorescent brightener, the whiteness value after fluorescent brightening can be quantitatively reflected. The opacity of paper can be measured accurately. It can be widely used in the whiteness measurement of textile printing and dyeing, paint, chemical building materials, paper and paperboard, plastic products, white cement, ceramics, enamel, talcum powder, starch, flour, salt, detergent, cosmetics and other substances.
Paper digital whiteness meter characteristic:
1. Microcomputer, touch keyboard, LCD backlight LCD, standard serial RS232 data communication interface.
2. Data nonlinear processing and data smoothing function, fast automatic multi-point correction, self diagnosis information prompt, rapid and stable response, maintenance free and reliable operation.
3. The color measurement performance of * * is extremely accurate. By using computer aided design, the overall spectral characteristics of the instrument fully conform to CIE standard observer response curve, and ISO whiteness can be obtained accurately.
4. The modified color filter system can quantitatively reflect the whiteness value * * wsb-2a after fluorescent whitening, which is simple to operate and can accurately measure the opacity of paper.
5. High stability and reproducibility, completely eliminate the system drift error, with data storage query function, can meet the requirements of GLP.
6. Imported original components, high efficiency, low loss switching power supply, reasonable and simple optical circuit design, good reliability.
