Under airtight settings, colour-changing silica gel is used to absorb moisture and resist corrosion on instruments, metres, and appliances. Simultaneously, by shifting the colour from blue to red after absorbing moisture, it may directly reflect the relative humidity of the region.
To signify the degree of moisture absorption of the desiccant and assess the relative humidity of the atmosphere, colour-changing silica gel is used in combination with regular silica gel desiccant. Precision tools, leather, shoes, garments, food, medication, and kitchen appliances all use silica gel desiccants as packaging desiccants.
