To tell you the working principle of dry wet bulb and reading methods

Dry wet bulb is usually used in greenhouses or farms. Today we are going to tell you about how to do the working principle of wet bulb and reading methods. Dry wet thermometer is made up of two thermometer, relative humidity, water bottle, including a thermometer by white gauze to cover the submerged, a not with gauze bag dew in the air. Used to dry wet first thermometer back bottom water bottle water, water to soak into the gauze. If just add water, 30 minutes later, can be reading. Or reading the number is invalid. Then read the dry bulb and wet bulb temperature, temperature difference calculation. The final check to find the corresponding humidity temperature and humidity table. For example, assume that the thermometer shows the temperature of the dry bubble is 22 ℃, wet bubble is indicated by the thermometer is 16 ℃, the difference in temperature between two bubble is 6 ℃, the temperature can be shown in the table first line found 22 ℃, and the temperature of a line to find 6 ℃, then the line 22 ℃ 6 ℃ vertical and horizontal alignment, find the number 54. It is the meaning of relative humidity is 54%.
