Reusable BTB Ammonia Leak Detection Cloth [One 20 inch x 20 inch Cloth]

Description The Ammonia Leak Detection Cloth is used for the detection of leaks in sealed incubators, such as those used for infectious disease studies and in the treatment of premature birth. Industrial uses for detection of ammonia gas include sealed containers and filtration systems including air tightness testing of glove boxes and pharmaceutical isolators. The cloth is sensitive to vapors and gas from a 1% solution of Ammonia (NH3). The Ammonia Leak Detection Cloth is reversible. As long as the cloth reverts back to the original goldenrod yellow color, it will continue to change when exposed to ammonia vapors. Eventually, it will not revert back to its original color and can no longer be reused. It works best if exposed to vapors. If the cloth gets wet, it will not be reusable. Instructions: Place the Ammonia Leak Detection Cloth near a suspected leak. The cloth will turn blue immediately upon detection.
