Features and Benefits

  • Pen changes colour according to the acidity level present
  • Easy to use: simply draw a small line on the material you wish to test. The Chlorophenol red indicator solution in the pen will turn purple on any paper with a pH of 6.8 and above. A clear or yellow colour indicates the material is probably unsuitable for conservation purposes
