How Do You Work Out Weather Temp?

There are all different kinds of thermometers to work out the weather temp. But to know the weather at any given time, a dry bulb thermometer is used. Instead of mercury inside this thermometer there is alcohol. There are also minimum temperature guages where the mercury, as the temperature declines, pushes an indicator to the coldest point. A maximum works much the same except that it pushes the indicator as the temperature increases so when you want to know the highest temperature and the lowest temperature of the day, you look at those to thermometers. They must be reset to the temperature of the dry bulb each morning though to ensure correct indications. A wet bulb thermometer is used to compare with the dry bulb thermometer to determine humidity.
