Answer 1

A psychrometer measures relative humidity by comparing the temperature in wet air and dry air. This is done using two thermometers: one with a dry bulb and one with a wet bulb. The difference in temperatures between the two bulbs, along with a psychrometric chart or formula, allows for the calculation of relative humidity.
