Johnson Universal Indicator Papers provide a quick way to estimate acidity or alkalinity in beer, wine, cider and spirit washes. Each book contains 20 test strips covering pH 1–11, with a colour reference chart for interpreting the result.

Checking pH with indicator paper

  • See the Johnson pH Test Strips – Book of 20 for the full specifications and usage guidance.
  • Use a clean sample rather than dipping a strip into the full batch.
  • Compare the developed colour with the chart promptly and under neutral lighting.

Indicator paper provides an approximate reading. Use a calibrated digital pH meter when your process requires greater precision.
