Review on Haobase Indicator Litmus Strips Tester: Accurate and Reliable Color Indicator Testing Tool by Bob Fasho

Not suitable for testing minor pH differences, e.g. B. Drinking water. However, it is ideal for teaching or for experiments and work with acids and bases for young people. It's fairly accurate and an unsupervised child can easily tell the difference. All litmus papers are the same. So if you need something more specific, use indicator papers, but any other litmus paper will do the same job. My students used them to test pH before studying acid-base reactions. Also good to use to learn extra fun crafts like making bath bombs. Edit: I see some people commenting on Chinese. What detailed instructions do you need for the product to be available in English? It is from a Chinese company and is not advertised otherwise. Feel free to spend more for a product that doesn't have Chinese.
