Dry wet bulb thermometer
WebApr 1, 2024 · A dry thermometer has the bulb exposed to air. A wet thermometer has the bulb covered with a muslin cloth which is dipped in water. It is used to measure the relative humidity of temperature. When air is saturated, evaporation stops and the two bulbs show the same reading. WebRelative Humidity is measured using a device called a sling psychrometer.This consists of 2 side by side conventional thermometers, one of which (the wet bulb thermometer) has a wetted wick placed at …
