Small Panel Mounting Desiccators is designed to protect electronics, electrical and computer equipment against corrosion, dampness and contamination. It incorporates a humidity indicator capable of monitoring moisture saturation, and its desiccator can also be filled with moisture adsorbing agent (either blue-indicating silica gel or molecular sieves).
When the blue-indicating silica gel is saturated with moisture, the desiccant will turn from blue to pink in colour.
The molecular sieve, on the other hand, is used to maintain an ultra-low relative humidity for extremely sensitive applications where equipment may fail to operate as a result of water vapour condensation. Molecular sieves are highly recommended for applications where equipment or enclosure require a low temperature to work, and water vapour condensation must not occur.
