The correct use of a thermometer to know the exact temperature

If you want to know every day in addition to pay attention to the weather forecast, the temperature changes and what way? Using natural thermometer is a right thing, we know there are many kinds of thermometer, understanding of the most common is indispensable, such as: the most common bimetallic thermometer, and household electronic thermometer, the summer, is the most commonly used glass rod thermometer outside, but the thermometer? How to correctly use the thermometer? We think, according to the measured temperature of the object is different, the use of the thermometer there are big differences and differences. Here, the problem of what is a thermometer, we from different measuring target to learn about the different ways of measuring. One, in the use of liquid thermometer thermometer when using the method, the correct method is as follows: 1, the upper end of the thermometer in hand, all the glass bulb thermometer into the liquid being measured, don't touch the bottom of the container or the container wall. 2, glass bulb thermometer immersed in liquid after being tested to wait for a moment, after waiting for thermometer readings stable reading again. 3, reading glass bulb thermometer to remain in the liquid, the liquid column in the line of sight with thermometer faces flat above. 2, temporary determination of indoor and outdoor temperature: 1, the upper end of the thermometer with your hands, such as liquid column within the thermometer when they stop lifting to readings; 2, readings, the line of sight to also want to and the hydraulic pillars of the thermometer at flat; 3, if long-term measure outdoor temperature, to hang the thermometer in the shaded ventilated place. One end of the thermometer with your hands, can avoid the hand of the temperature of the liquid in the table. If the glass bulb thermometer run into the bottom of container or wall, determination is not water temperature; Within the range if the thermometer liquid column to stop lifting is reading, or out of the water when reading, the reading is not the real temperature of water. ） Note: don't jilt before measuring temperature.
