کلرید کبالت، ماده جذب کننده رطوبت که به رنگ آبی است و زمانیکه رطوبت را به خود جذب کرد صورتی رنگ میشود.
A dye used with silica-gel in a dehydrator to indicate the presence of moisture. When cobalt chloride is dry, it is deep blue in color, but when it absorbs water, it turns pink. If a dehydrator element is blue, the component it protects is dry. But if moisture gets into it, the silica-gel absorbs some of the moisture, and the cobalt chloride turns pink.
