LCD Displayed ISO Whiteness Meter For Paper Testing Machine
Digital whiteness meter is used to test the whiteness of no-color substance with flat surface or powder. And this type paper testing mahine can gain a coherent whiteness with sensation correctly. and It can also reflect the whiteness value after fluorescent brightening finished quantitatively, toward fluorescent brighten substance. It can also measure the transparent property of the paper.
It is widely used in whiteness measurement of textile dye, paint, chemical & building material, paper, plastic products, white cement, ceramics, talc powder, flour, salt, detergent, cosmetics.

1. Design by CAD computer assistance makes the appearance more reasonable and perfect.
2. Adoption of high efficiency, low loss switch power makes it more reliable.
3. Imported high quality parts make work more stable and life more durable.
4. Simple optical design makes usage and maintenance briefer.
5. Correctional color filter system can reflect the whiteness value quantitatively after fluorescent brightening. 
6. Reasonable design of the sample table and movable platform can avoid light leakage at the measuring orifice.
7. Easy operation can measure the transparent property of the paper
