A large range of humidity indicator plugs are available. These externally mounted color change humidity indicators are for determining relative humidity inside rigid containers, electronic enclosures, optical cavities and flexible moisture-vapor-proof bags. The DT1 series can be used in conjunction with a static type desiccator. Mounting options include thread mounting into enclosure, panel bushing or crimp nut.

RFI humidity indicators plugs are also available by request.
Check thread size on static desiccator for campatibility with thread A
