The Color-Changing "Humidity Detector" - Indicator Silica Gel
Among various desiccants, indicator silica gel has emerged as a shining star due to its unique color-changing ability. It not only efficiently absorbs moisture but also can accurately report the environmental humidity status through its intuitive color changes, just like a loyal "humidity scout".
The core mystery lies in the addition of the magical "indicator" - cobalt chloride. In a dry state, cobalt chloride exhibits a captivating blue color. As it begins to absorb moisture from the air, the number of its own crystalline water molecules changes, resulting in a color change. When it reaches saturation, it turns pink or light purple. This distinct and reversible color-changing reaction provides us with the most intuitive humidity warning.
