China Flour Color Grader

WGB-1 Digital Whiteness Meter
1 Summary of functions
The digital whiteness meter is mainly used to measure the whiteness of non color surface or near white flat object or powder, and 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. Wbd-1 digital whiteness meter has the advantages of accurate measurement, exquisite design and extremely stable performance.
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, measurement, commodity inspection, detergent, cosmetics and other substances.

ZB-B Whiteness Meter
Normal Type
Product Overview of Whiteness Meter
ZB-B whiteness tester is a special instrument for measuring whiteness of objects. It is widely used in the whiteness measurement of paper board, textile printing and dyeing, paint, chemical building materials, plastic products, cement, calcium carbonate powder, ceramics, enamel, porcelain clay, talcum powder, starch, flour, salt, detergent, cosmetics and other objects.
The specific functions of the instrument are as follows:
1. The ISO brightness (R457 whiteness) can also be measured for fluorescent whitening samples.
2. Measure the value of lightness stimulation.
3. Measure the opacity.
4. Measure the transparency.
5. Measure the light scattering coefficient and absorption coefficient.
6. Measure the ink absorption value.

Main Performance Parameters
1. The instrument has novel appearance, compact structure and advanced circuit design, which can effectively ensure the accuracy and stability of measurement data.
2. The instrument simulates D65 illumination.
3. The instrument uses D / O illumination to observe geometric conditions. The diameter of diffuse ball is 150 mm, and the diameter of test hole is 30 mm (19 mm). A light absorber is set to eliminate the influence of mirror reflection light of sample.
4. The LCD module with large screen and high pixel is used to display the operation steps in Chinese and display the measurement and statistical results. The friendly man-machine interface makes the operation of the instrument simple and convenient
5. A printer is added to the instrument and imported thermal printer core is adopted, which has the advantages of no ink and ribbon, no noise and high printing speed
6. The instrument is equipped with standard RS232 interface, which can communicate with microcomputer software
7. The instrument has power-off protection, and calibration data will not be lost after power failure
