A hair hygrometer.
100% because, let's say that both the thermometers have a reading of 66o degrees celcius. 66o is 100% of 66o, so the relative humidity is 100%.
A hygrometer measure humidity. One sort of hygrometer is psychrometer, it has two thermometers one kept wet the other dry. The difference between the temperatures is related to the humidity.
An anemometer measures wind speed. A hygrometer measures relative humidity. Two different things entirely.

Water vapor in the air is absolute humidity. The ratio of the absolute humidity to the maximum absolute humidity for that temperature and pressure is called the "relative humidity." Absolute humidity is very frequently expressed in terms of grains per pound of air, ppm, or vapour pressure. Relative humidity is usually expressed as a percent.Relative humidity, expressed as a percentage from 0% to 100%, is the amount of moisture in air divided by the total possible amount of moisture in air. Unfortunately, the total possible amount changes when the temperature changes, so the relative humidity can change without adding or removing any water.Another measure is dew point, which is the temperature at which water would condense. It doesn't change with temperature.The lowest measured relative humidity in Phoenix, AZ, USA, is 2%--pretty dry. Sometimes the dew point is below 0 degrees, also pretty dry. (Celsius or Fahrenheit? Both!)

It is a hygrometer.
Psychrometers are used for measuring the dew point and relative humidity which you have to have a chart to find and finding the relative humidity in controlled environments
humidity is moisture in the air and is measured with a hygrometer

2 instruments are required to accomplish these measurements:a barometer to measure atmospheric pressure.a hygrometer to measure humidity.
A phsychrometer measures relative humidity
Your question is a little unclear. The devices used to record temperature and relative humidity are "thermometers (temperature)." and "hygrometers (relative humidity)". Sorry if this isn't what you were looking for.
A hygrometer measures humidity. Don't confuse it with a hydrometer which measures density.
