Indicating silica gel packets are ideal in applications where visual control of moisture is required. The silica gel turns from orange to green as it adsorbs moisture, indicating the need for replacement. The packets work by adsorbing and trapping moisture from the air, lowering humidity and preventing the formation of mould, condensation & rust in enclosed spaces. Silica gel can adsorb up to 40% of its weight in moisture while remaining dry to the touch. It will remove moisture at temperatures as high as 60°C, but it is best used at room temperature (20‐35°C) and high relative humidity (60‐90% RH).

Packet material is made from non-woven cloth and includes an inspection window for easy viewing of the colour changing silica gel.
