Indicating silica gel is unique because it is treated chemically to make the transition possible from one color to another. It absorbs moisture and gradually becomes absolutely drenched in it. This characteristic of indicating silica gel makes it remarkable for absorbing moisture from the surrounding environment it is placed in. Their colors change when the Indicating desiccants are soaked with the surrounding moisture. Hence, indicating to the user that it is high time to replace or recharge the desiccants. Not only this but Indicating silica gel also has the feature of a rapid detection process that makes it easy for the user to determine the life of desiccants instantly. You can recharge or replace the indicating silica gel when it is out of working efficiency. And, as the name suggests, non-indicating desiccants do not have this quality to change their color. That is why it makes it difficult for the user to determine the quantity of moisture absorbed by their desiccants. There are two types of indicating silica gel.
