Morphology

wet-bulb + thermometer

The compound is directly compositional: 'wet' (moist) + 'bulb' (the rounded part) modifies 'thermometer' (an instrument), so a learner who knows the constituents can infer it is a thermometer with a moist/wet bulb. Although the specific use (measuring humidity) is somewhat technical, the referent and basic function are transparently derivable from the parts and typical noun-compound patterns.

Etymology

The noun wet-bulb thermometer is a thermometer whose round end, the wet-bulb, is wrapped in a wet cloth so the air cools it as the water dries. By comparing the cooled wet-bulb reading with a normal dry thermometer, people can tell how much moisture is in the air, so it is used to 'measure humidity'.
