Panel mounted desiccators provide protection against corrosion, dampness and contamination in electronic, electrical, telecommunications, computer equipment etc. These desiccators incorporate a humidity indicator, which monitors saturation and indicates when desiccant change or cartridge replacement is required. They are blue when the desiccant is dry and turn pink when the maximum amount of moisture has been adsorbed.
A powerful adsorbing agent (either silica gel or molecular sieves) reduces the existing or incoming moisture to acceptable levels. The use of molecular sieve desiccant is recommended when the equipment may be subject to immediate failure as a result of water vapour condensation. The molecular sieve desiccant maintains an ultra low relative humidity for extremely sensitive applications. It is most suitable for applications where equipment or enclosures may be subject to operation at low temperatures and water vapour condensation must not occur.
This style of desiccator are combined with a single relative humidity indicators which are a visual indication of when the desiccator has fully adsorbed.
All have the same 3/4 x 2OUNS-2A thread but vary in length.
The desiccant cartridge can be unscrewed from the humidity indicator plug went spent and replaced with a fresh unit.
