Blue indicator silica gel desiccant pack
Compared with ordinary silica gel desiccant, blue indicator silica gel desiccant not only has the function of moisture absorption, but also contains an indicator, usually small blue or purple blue particles, which can show the degree of moisture absorption through color change, which is convenient User monitoring. When the blue color indicates that the silica gel desiccant has absorbed moisture, the color of the indicator will gradually become lighter until it turns pink or white, indicating that it has reached moisture saturation and needs to be replaced or dried for reuse. Therefore, the blue indicator silica gel desiccant is usually widely used in occasions that need to monitor humidity, such as storing cameras, electronic equipment, optical instruments, etc.
