Use wet and dry bulb thermometers.

A physcrometer is the tool you want.

Hello Benn,
There are dry and wet bulb thermometers on the market:
14628
With electronic instruments it's not usual, normally there are temperature and humidity sensors, and then you can calculate the wet bulb temperature if you need it.
