1. Used for absorbing moisture of instruments, gauges and equipment in the enclosed conditions.

2. After adsorb moisture, it turns blue into red, visually indicating the relative humidity of the given environment..

3. When being used with ordinary silica gel or drier, it indicates to which extent the drier absorbs the moistures and judges the relative humidity of a given environment.

4. Used to judge if the humidity of a environment is up to the specified requirements and to determine if the adsorbent or drier ceases to be effective.
