dewpoint apparatus
A calorimeter measures heat. In contrast, a thermometer measures temperature.A thermometer bolometer - an instrument that measures heat radiation; extremely sensitive calorimeter - a measuring instrument that determines quantities of heatHeat is measured with a ThermometerThermometerThermometer or calorimeterThermometerthermometerHeat is measured with a thermometer.
The process of water turning into gas (water vapor) is called evaporation.Heating water into water vapor is called boiling. High-temperature water vapor is called steam.The water has become water vapor.

A spring scale measures weight.
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.
dewpoint apparatus
I'm almost certain a hygrometer measures water vapor in the air.
Water vapor in the air is practically the same as measuring the humidity that is in the air.

A Hygrometer. It measures Relative Humidity.
it measures the water vapor content of air or the humidity.
