Meteorological Dry and Wet Bulb Thermometer produced by Beijing Pute Instrument Complete Factory -: It is an instrument for measuring temperature and humidity.
-: The wet and dry bulb thermometer is composed of two thermometers of the same model. The thermometer is made based on the thermal expansion and contraction properties of mercury (alcohol). It is divided into four parts: sensing bulb, capillary tube, scale magnetic plate and outer sleeve

-: Mankind invented the wet and dry bulb hygrometer in the 20th century. The accuracy of the wet and dry bulb hygrometer also depends on the accuracy of the dry bulb and wet bulb thermometers themselves. The hygrometer must be in a ventilated state: only a gauze water jacket, The specified accuracy can only be achieved when water quality and wind speed meet certain requirements. The accuracy of the wet and dry bulb hygrometer is only

% -> -:Principle of wet and dry bulb hygrometer
-:
% -> -The dry ball probe of the wet and dry bulb thermometer is directly The wet bulb temperature probe exposed in the air is wrapped with wet gauze. The principle of humidity measurement is that at a certain wind speed, the water in the wet gauze outside the wet bulb evaporates and takes away the heat on the wet bulb thermometer probe, making the temperature lower than the temperature of the ambient air. What the dry bulb thermometer measures is the actual temperature of the ambient air. At this time, the temperature difference between the wet bulb and the dry bulb has a corresponding relationship with the relative humidity of the environment, but this relationship is non-linear. It's quite complicated to express in a formula. The relationship between the two will be affected by many factors, such as: the accuracy of the anemometer itself, the atmospheric pressure, the bulb surface area of the wet and dry bulb thermometer, the size of the gauze material, etc.
