Blue Indicating Desiccant
Indicating desiccant is ideal for use with moisture-sensitive products that are subject to regular inspection because it gives a quick indication of the saturation level of the desiccant.
Indicating silica gel is a bead or granule that has been washed with a concentration of cobalt chloride (a heavy metal salt). The cobalt chloride is a deep blue color when dry and turns from blue to pink as it becomes saturated with moisture.
