Indigo® cobalt chloride moisture indicator strips have a variety of uses. They indicate the presence of water by changing color from blue to pink at 50% relative humidity or higher. Use them to detect moisture in tiny cracks & crevices from masonry to circuit boards to science lab experiments in plant transpiration & combustion.
See our blog about water leak detection for more information or watch our video Water Leak Problems?. Available also in larger 8x10" (200x250mm) sheets for use in showing splash patterns. Extra large sheets up to 20x24" (500x600mm) can be ordered but there is a 100 sheet minimum.
