Lineco Ph Testing Pen

"

Lineco pH Testing Pen provides a quick and convenient way to determine whether paper and paper-based materials are acidic or alkaline. Designed for artists, framers, conservators and collectors, this easy-to-use pen helps identify materials that may be unsuitable for long-term archival storage and preservation.

Simply draw a small mark on the paper surface and observe the colour change. A purple mark indicates neutral or alkaline paper, while a yellow or clear mark indicates acidity. Ideal for evaluating papers, mounting boards, scrapbook materials and other paper products, the Lineco pH Testing Pen is a practical tool for making informed decisions about archival framing and storage.

Testing may leave a permanent mark, so use on an inconspicuous area or sample rather than directly on valuable artwork or documents.
