R.F. Screened for Equipment & Enclosures

Description

R.F. Screened Humidity Indicators are best suited for mounting on moisture-sensitive electronic, electro-optic equipment or any humidity-controlled enclosure that requires EMC Shielding. These units can detect changes in the humidity 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.

These Humidity and Electronic Indicators are available in several models:
