The development and production of this product are based on blue indicating silica gel, which is made by impregnating fine-pore silica gel with an inorganic salt solution to produce orange indicating silica gel. It utilizes a new type of non-toxic composite dye, fundamentally eliminating environmental pollution caused by dyes and color-changing agents. With its unique technological conditions and excellent adsorption performance, the product represents a new generation of environmentally friendly products.

This product is primarily used for drying and indicating the saturation level of desiccants, as well as for maintaining the relative humidity in sealed packaging and the internal environment of precision instruments and meters. It is also used for moisture protection in general packaging and instrument systems. It can be used alone as a desiccant or in combination with fine-pore silica gel. It provides moisture protection for instruments and meters and can be used either independently as a desiccant or together with fine-pore silica gel.
