R.F. Screened for Equipment & Enclosures

R.F. Screened Humidity Indicators for Equipment & Enclosures are best suited for mounting on moisture-sensitive electronic, electro-optic equipment, or any humidity-controlled enclosure that requires EMC Shielding. These units detect changes in humidity by using a color-changing indicator paper that turns from blue to pink when humidity increases and reverts to blue when the humidity decreases. These indicators can be fitted with a desiccant cartridge, also known as static desiccators, to adsorb any moisture entering the equipment during usage.

These R.F. Screened Humidity Indicators for Equipment & Enclosures are available in several models:
