R.F. Screened for Equipment & Enclosures

The R.F. Screened Humidity Indicator Plugs are designed to be mounted in moisture-sensitive electronic equipment or humidity-controlled enclosures that require EMC Shielding. The R.F. Screened Humidity Indicator Plugs feature a humidity sensor that changes colour depending on the humidity level. When the humidity level increases, the humidity sensor changes colour from blue to pink but reverts to blue when the humidity level decreases. Most of these indicators can be fitted with a desiccant cartridge which adsorbs and remove moisture entering the equipment during use.

Here at Stream Peak, our R.F. screened for equipment & enclosures are available in several models:
