The water indicator paper sheets shown in the image are 8x10" (200x250mm). The native color of the sheets is yellow & the wetted sections turn red when exposed to liquid water. They are insensitive even to high humidity levels unlike the cobalt chloride papers.
Note: Chlorophenol red does NOT change color if the water is below pH 5.5. If you require a permanent record of water leakage at pH levels below this, we recommend the universal pH water indicator paper.

This water detection paper worked well in identifying moisture intrusion during testing and was easily observable due to its high color contrast.
