Stream Peak offers a comprehensive range of Humidity and Electronic Indicators for Equipment designed applications that include mounting moisture-sensitive electronic or electro-optic equipment or any other humidity-controlled enclosure. This equipment can detect humidity changes in the space monitored through a colour-changing indicator paper that turns from blue to pink when humidity rises, reverting to blue when 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.
