Dry bulb wet bulb thermometer
WebA psychrometer has two thermometers. The dry bulb thermometer measures air temperature. The second thermometer has. a wet bulb. As water evaporates from the wet bulb, its temperature decreases relative to the air temperature. 1. Do you think the wet bulb will cool down more on a dry or humid day : Maybe on a dry day. 2. WebJul 1, 2024 · The psychrometer (q.v.) is a hygrometer that utilizes two thermometers—one wet-bulb and one dry-bulb—to determine humidity through evaporation. A wetted cloth wraps the wet-bulb thermometer at its enlarged end. Which instrument is used for measuring temperature and relative humidity?
