Small Indicators for Equipment

Description

These small humidity indicators are ideal for mounting applications on moisture-sensitive electronic, electro-optic equipment or any humidity-controlled enclosure. These units detect changes in the humidity by using a colour changing indicator paper that turns from blue to pink when humidity increases, reverting to blue when the humidity decreases.

Most of these indicators can be fitted with a desiccant cartridge, also known as static desiccators to adsorb any moisture entering the equipment during usage.
