Small Indicators for Equipment

The Small Indicators for Equipment are made for mounting in smaller moisture-sensitive equipment and enclosure, and these indicators can detect relative humidity changes of the space readily. When the humidity level increases, the indicator will turn from blue to pink, reverting to blue when relative humidity decreases. Most Humidity Indicator Plugs are fitted with a desiccant cartridge that adsorbs and removes any moisture entering the equipment during use.
