Humidity indicators for electronic or electro-optic equipment and other humidity-controlled enclosures where moisture sensitivity is a concern. These indicators detect alterations in the humidity levels of the monitored space by utilising a colour-changing sensor paper.

As humidity levels rise, the paper turns from blue to pink, and when the humidity levels drop, it changes back to blue. The humidity indicators are compatible with a static desiccator filled with silica gel or molecular sieve desiccants, which can absorb any moisture that may infiltrate the equipment during operation.
