A hygrometer is an instrument used to measure the quantity of water vapour present in air.
Hygrometers can measure relative humidity over the range of 0 to 100% RH but this range may be more limited depending on the sensor type.
Relative humidity is expressed as the ratio of the amount of water vapour present in the air or gas, to the quantity which would reach saturation, saturation being 100%.
