Universal pH paper offers a permanent record of water leakage & is best where different pH levels need to be indicated. Comes in 8x10" (200x250mm) sheets for only $2.95; quantity discounts.

Universal pH paper available in large format 24x20" (600x500mm). Mininum order is 100 sheets.  Other custom sizes available; MOQ applies.

Use Chlorophenol Red Water Leak Detection Paper for permanent and very distinctive water indication except where water pH is below 5.5.  Cobalt Chloride Leak Detection Paper reacts at relative humidities above 55% so can detect water vapor as well as liquid water.

Details

What is Universal Indicator Made of?

  • Phenolphthalein
  • Methyl Red
  • Bromothymol Blue
  • Thymol Blue

The native color of the sheets is orangish-yellow but changes at different pH levels due to the various indicators. This makes it useful as both a pH indicator & water leak detector.

The universal pH water indicator paper sheets shown in the image are 8x10" (200x250mm).

Specifications

Use these when you want to confirm not just a liquid water leak but also if the source is acidic or alkaline such as battery acid or lye or even wine. They can also be used in place of chlorophenol red paper which does not change color below ~pH 5.5-6.
