Background technique

Today's thermometers on the market can be roughly divided into two types: mercury thermometers and electronic thermometers. These two types of thermometers are used by enthusiasts according to their usage habits.

A general mercury thermometer consists of a glass rod and a mercury column set inside the glass rod. The degree of rise of the mercury column will depend on the degree of heating. After the mercury column rises to a certain scale, it will stop rising. , the data indicated at the end of the mercury column is the correct body temperature reading, so the temperature value of the mercury thermometer is visually displayed as a column-shaped image, which is convenient for the user to read the value; On the one hand, the electronic thermometer uses a temperature sensing element to sense temperature, and then displays the sensed temperature on a screen in digital form.

However, since the mercury thermometer uses the length of the mercury column to display the temperature, it needs to have a certain overall length, and it is difficult to read the data, and the accuracy is low. Therefore, the electronic thermometer has gradually replaced the mercury thermometer. , has become one of the household necessities; for users who are accustomed to mercury thermometers, the existing electronic thermometers can only simply display numbers, and their temperature display is quite different from that of mercury thermometers, which in turn affects the acceptance of some users .
