Use the Lineco pH Testing Pen to test paper products for acidity. It provides an easy method to distinguish between acid-free and unsafe acidic materials. The chlorophenol red solution in the pen will turn a purple/lavender colour on acid-free or neutral paper with a pH of 6.8 or above. A yellow or colourless result indicates the paper is acidic.
