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.
No. A psychrometer measures relative humidity.
A psychrometer is an instrument commonly used to measure the relative humidity.
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
Straight human hair is used in a hair hygrometer. Its length depends upon the relative humidity. First drawn by Leonardo da Vinci about 1450.
%
No units - its a ratio.
Fahrenheit or Celsius or Kelvin. Ex: 65ºF, 32ºC, 100ºK

There is no such thing as a sygrometer, but a hygrometer is a device that is used to measure the humidity of the air. It can indicate relative humidity or absolute humidity.
Relative humidity expresses a percentage of humidity in the air to the maximum amount of humidity that could be in the air. For example: when the temperature rises the air will be able to hold much more humidity so the relative humidity will drop.
hygrometer used to measure density of relative humidity in air by using a sensory element such as a hair
barometer A barometer measures atmospheric pressure, not humidity. A hygrometer measures humidity.
No. A psychrometer measures relative humidity.
