Is the monitor humidity 95 very humid?
The most primitive hygrometer is like the old medical hygrometer, which measures the dry bulb temperature and then compares it with the wet bulb temperature. When the temperature is constant, the difference between dry and wet is large, indicating that the humidity in the air is small), find out the actual relative humidity value in the dial, and you can know the current humidity state of the air.
Basic form of humidity
There are three basic forms of humidity, namely water vapor pressure, relative humidity and dew point temperature.
Water vapor pressure (once called absolute humidity) indicates the pressure of water vapor in the air, in hectopascals, with one decimal place reserved;
Relative humidity is expressed as the percentage of the ratio of actual water vapor pressure to saturated water vapor pressure in the air at the current temperature, taking an integer;
Dew point temperature refers to the temperature when the water vapor content in the air and the air pressure reach saturation during cooling. Units are expressed in degrees Celsius (℃), with one decimal place reserved. When equipped with a hygrometer, it can also measure the continuous record of relative humidity and minimum relative humidity.
