Orange Indicating Silica Gel gradually changes from orange color in the activated condition to to green color in the saturated condition. It can be reactivated by heating at 250-450oF, in a clean atmosphere until it becomes orange again. It meets the requirements for the European Union RoHS.
Orange Indicating Silica Gel is widely used as a relative humidity indicator in dehydrated packages or air drying equipments. It is used as a combination desiccant-relative humidity indicator.
