A humidity monitoring device is called a hygrometer. Hygrometers may be designed for indoor or outdoor humidity monitoring use (or both). Below is a summary of the types of hygrometers available for measuring humidity. Analog hygrometers use a moisture-sensitive material that is attached to a coil spring.
Relative humidity, expressed as a percent, measures the current absolute humidity relative to the maximum (highest point) for that temperature. Specific humidity is a ratio of the water vapor content of the mixture to the total air content on a mass basis. What I get from that is RH is % of what water can fit into that temperature and pressure [which means absolute humidity]. Specific Humidity is weight of water divided by total air weight.
