Chlor Phenol Red (CPR) 8 in x 10 in Test Paper Sheets [Pack of 24]

Description

• Large Coverage, Precision Detection: Oversized 8” x 10” sheets efficiently cover large surfaces, making it easy to locate water leaks and pinpoint their exact source.
• Customizable for Any Space: Cut the sheets into smaller strips to access tight, hard-to-reach areas for maximum versatility in leak detection.
• Instant, Visual Leak Detection: Watch water exposure turn the paper from yellow to vivid red or purple, providing a clear, dramatic indication of leaks.
• Dual Functionality for pH Analysis: Detect water leaks while also distinguishing pH differences — easily identify if a liquid is neutral, acidic, or basic.
• Humidity-Resistant Performance: Unlike cobalt chloride papers, these sheets stay unaffected by high humidity, ensuring reliable, accurate results in challenging environments.

Chlorophenol red water leak detection paper dramatically indicates the presence of water with a bright red color. The water indicator paper sheets shown in the image are 8×10″ (200x250mm). The native color of the sheets is yellow & the wetted sections turn red to a deep purple (depending on the liquid’s pH) when exposed to liquid water. They are insensitive even to high humidity levels unlike the cobalt chloride papers.

Chlorophenol Red (CPR) test paper is useful in differentiating between a solution with an acidic pH and one with a more neutral pH. The unreacted paper is yellow/orange in color. At neutral pH (about 6.7) the paper will turn a reddish color. At higher pH values, the paper will turn more violet. Given that the paper starts out yellow/orange and turns red at roughly the pH of water, it is useful in finding water leaks.

Instructions for use:

1. Remove one Chlorophenol red test paper sheet from the packaging, being careful not to touch the sheet anywhere other than where you grasp it.
2. Dip the sheet into the solution to be tested for 1-2 seconds and remove. Alternatively, place the test sheet near a seal where you suspect there might be a leak. Note: Do not dip the sheet directly into a solution that may later be consumed. Always test a sample of the solution and discard it when finished.
3. The test paper will turn red/violet in seconds if dipped into a solution that is neutral (pH ~ 7) or basic (pH >7).

NOTE: The solution must be water-based or no reaction will occur.
