Containers & Flexible Barriers

These humidity indicators are best suited for mounting on moisture-sensitive electronic, electro-optic equipment, flexible barriers or any humidity-controlled enclosure. These units detect changes in the humidity by using a colour-changing indicator paper which turns from blue to pink when humidity increases and reverts to blue when the humidity decreases.

For additional desiccant protection, we suggest using a desiccant port and silica gel or molecular desiccant bags.
