Relative Humidity – Temperature in Celsiusīelow table used to estimate the relative humidity of air if dry and wet bulb temperatures are known.ĭry Bulb Temperature = T db / Wet Bulb Temperature = T wb Relative Humidity – RH ( %) Meteorologists have worked out charts of these differences for each degree of temperature so that the observer can find relative humidity easily. If the surrounding air is holding as much moisture as possible – if the relative humidity is 100% – there is no difference between the two temperatures. If the surrounding air is dry, more moisture evaporates from the wick, cooling the wet-bulb thermometer more so there is a greater difference between the temperatures of the two thermometers. Then the temperatures of both thermometers can be read. During the whirling, the water evaporates from the wick, cooling the wet-bulb thermometer. When a reading is to be taken, the wick is first dipped in water and then the instrument is whirled around. One thermometer is ordinary, and the other with a cloth wick over its bulb is a wet-bulb thermometer. The simplest hygrometer – a sling psychrometer – consists of two thermometers mounted together with a handle attached on a chain. Hygrometer usually used for measured the air relative humidity. The plastic case of the instrument equipped with conversion scale for calculating the percent relative humidity. ![]() Description TQC Bacharach Sling Psychrometerīacharach type sling Psychrometer for indicating percent relative humidity on the basis of the wet bulb-dry bulb thermometer principle.
