Product Description
500g Blue/White Indicating Silica Gel Packets
Help control moisture inside sealed storage and packaging with 500g blue/white indicating silica gel packets. Each non-woven sachet combines blue indicating beads with white silica gel, providing a visible guide to check the desiccant during use.
How the Blue Indicator Works
The blue beads change towards pink as they adsorb moisture. The white beads stay white and do not indicate moisture uptake. Inspect the indicating beads through the semi-transparent sachet and replace used packets as needed. The colour is a guide to the desiccant condition, rather than a precise humidity reading.
Applications
Use with dry goods in well-sealed, moisture-resistant packaging for tools, machinery components, electrical equipment, optical equipment and other industrial goods. These large sachets help reduce humidity in the enclosed air during storage and transport.
