Lineco’s pH Testing Pen


[Lineco] A trademark for a pen containing a pH indicator dye. Lineco's pH Pen contains chlorophenol red indicator solution. When a small dot of ink is applied to a dampened paper, it will produce a color that is an approximate indication of its acidity or alkalinity. A pH greater than 6.8 gives a violet color while acidic pH levels below 5.2 are yellow. The dye residue leave a permanent stain on the paper and should not be used on a work of art. However, it may be useful for matboards, lining paper and hinges (King et al 1970).
