  • Device and method for detection/indication of liquid leakage
    Patent number: 7213534
    Abstract: An improved device for the detection of leakage is achieved when the device includes at least two components, of which at least one is capable of migrating with the liquid within the carrier, and forming a distinct color or other detectable signal with the first component. Such device is not sensitive to normal, ambient humidity and the color signal formed is resistant to being diluted or rinsed away in cases of abundant or repeated leakage.
