It is an optional accessory that replaces the top pressure gauge on the dryer, and its job is to tell you when a cartridge change is due instead of leaving you to guess. It is a relative humidity indicator, not a dew point monitor, so treat it as a maintenance signal rather than an air quality measurement.\u003c\/p\u003e\u003ch3\u003eHow it works\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eThe gauge reads relative humidity from 10 to 80% along with temperature from 20 to 100°F at the 1\/4\" NPT port.\u003c\/li\u003e\n\u003cli\u003eRecord the humidity together with the temperature, for example 40% at 80°F, because relative humidity shifts with air temperature.\u003c\/li\u003e\n\u003cli\u003eA new, dry desiccant cartridge typically reads about 30 to 35% relative humidity at 70°F (roughly 21°C).\u003c\/li\u003e\n\u003cli\u003eThe reading climbs as the cartridge takes on moisture.
