A check pen that can easily distinguish between neutral paper and acidic paper.
The "Astro Neutral Paper Check Pen" is a product that allows for easy differentiation between neutral and acidic paper. Traditionally, concerns have been raised about the preservation issues of commonly used acidic paper (such as yellowing and damage due to oxidation), leading to a significant increase in the use of neutral paper. In places where books are managed, it is used to identify important documents made from acidic paper so they can be recreated using neutral paper, or to reconsider the management methods of books. In the printing industry, it is used to prevent printing troubles by easily distinguishing between acidic and neutral paper, which have different printing suitability. 【Features】 ■ Allows for differentiation of neutral paper without the use of pH meters ■ Lightly apply the reagent to the paper you want to identify, and differentiation can be made based on the color *For more details, please refer to the PDF document or feel free to contact us.
