Humidity indicator plugs are ideal for mounting on moisture-sensitive equipment, electro-optic devices, flexible barriers, and any humidity-controlled enclosure. The plugs come with colour-changing indicator paper to detect changes in humidity. The paper turns blue to pink as humidity increases and reverts to blue when the humidity decreases.
For added protection against moisture, use a desiccator filled with silica gel desiccants or molecular sieve with humidity indicators. This will further ensure that moisture-sensitive equipment and devices remain dry and functional.
- Clear window to observe and monitor change in humidity level
- Distinctive colour change indication
- Reversible and non-reversible options
- Available in plastic or metal housings
