There are several kinds of thermometers, mercury thermometers and electronic thermometers are used to measure the temperature close to the armpits, and infrared thermometers are directly pressed to sense the temperature and display.

A thermometer shows 38 degrees Celsius, and if there is no throw, take the temperature of a lady with a temperature of 38 degrees Celsius, and the measurement result is 38 degrees.
Give it to someone at 39 degrees Celsius and it turns out to be 39 degrees.
Because the thermometer has a disconnected mercury bar. When the thermometer leaves the human body, the outside temperature is low, and the mercury shrinks in volume when it is cold, and it is disconnected in the narrow curved neck, so that the part of the mercury that has risen into the tube cannot be returned, and the height of the mercury column when it is in contact with the human body is still maintained. Therefore, although the body temperature of a person is low, the thermometer cannot return to a place lower than 38 degrees.
As a result, the body temperature measured was the same as the previous reading of 38 degrees.
But it can go to a higher temperature, so people with 39 degrees can measure normal body temperature.

The use of the thermometer is as follows: first, shake the thermometer, the mercury column drops below 36, then put the thermometer under the armpit, wait for 3-5 minutes, and finally read the number on the thermometer.
A thermometer is a maximum thermometer that records the highest temperature that the thermometer has ever measured. After use, the thermometer should be "returned to the table", that is, the upper part of the thermometer should be thrown down forcefully, so that the mercury that has risen into the tube can be returned to the glass bubble. Other thermometers should never be shaken, which is a major difference between thermometers and other liquid thermometers.

First throw the mercury back into the glass bubble, and then use an alcohol disinfectant cotton to detoxify the glass bubble, you can start to measure, you can put it at the base of the tongue, armpits, etc. (depending on what kind of thermometer you are placed in), wait for 5 minutes or 3 minutes to take it out and read, be careful not to break the glass bubble when measuring.
-
Hold the tail of the thermometer and shake it vigorously a few times to throw the mercury back to the head of the thermometer, and you can also observe that the scale where the mercury arrives is below 36 degrees. Hold the head of the thermometer (where there is mercury) under your armpit for 5 minutes. Take out the observation and twist the scale with your hand facing you, and you can observe the scale where the mercury arrives.
Above 37 degrees Celsius is a fever. The normal temperature of the human body is 37 degrees. You can also hold the head in your mouth, but be careful not to break it, otherwise swallowing mercury is life-threatening.

1. Before measuring, observe the thermometer to be used to understand its range (measurement range) and graduation value (the corresponding temperature value of each small grid);
2. Make the glass bubble of the thermometer fully in contact with the measured liquid during measurement (to be immersed in the measured liquid);
3. Wait for the indication to be stable before reading;
4. When reading, the glass bubble of the thermometer should be left in the liquid to be measured, and the reading should not be taken out.

Proper use of commonly used thermometers:
Before use: 1) See the range of the thermometer, judge whether it is suitable for the temperature of the object to be measured, and avoid damaging the thermometer;
2) Recognize the index value and zero scale mark of the thermometer for accurate reading.
When using: 1) The glass bubble of the thermometer is fully immersed in the liquid to be measured (that is, it is in full contact with the object to be measured), and do not touch the bottom or wall of the container;
2) The glass bubble of the thermometer is immersed in the liquid to be measured for a while, and then the reading is carried out after the thermometer is stable;
3) The glass bubble of the thermometer should continue to remain in the liquid to be measured during reading, and the line of sight should be level with the upper surface of the liquid column in the thermometer.

Preparation materials: mercury thermometer.
1. First of all, you need to go to a regular medical device store to buy a body temperature version, the thermometer has mercury thermometer, electronic thermometer, etc., and you can choose according to your needs.
2. Before using the thermometer, hold the mercury thermometer in your hand and throw it down vigorously to lower the mercury column.
3. When measuring, you can put the metal end of the thermometer under the armpit, and then clamp it.
4. The thermometer can also be put in the mouth, just hold it gently, don't be nervous, don't bite hard.
5. The thermometer can be taken out after 3-5 minutes of resting on the body, and then look at the value on the thermometer, which must be parallel to see clearly.

Mercury thermometer which end to put under the armpits.
-
Put the iron side under your armpit and shake it with the end that you held before that was not mercury. Throw it to 30 degrees, pinch both ends of the thermometer with both hands when reading, (don't pinch the mercury tank), the end is flat, slowly rotate inward or outward, and you can read clearly when the glass refracts the mercury bars thicker.
-
If you want to use a thermometer, you must first check whether the thermometer is damaged, shake the thermometer a few times, put the metal head under the armpit and clamp it, and then take out the thermometer after 10 minutes. Pinch the tail end of the thermometer with your hand and take it out slowly, and the mercury column line you see is the temperature value, and you should wipe it with an alcohol cotton ball after use.
Be careful when measuring your body temperature with a thermometer, be careful when taking the thermometer, and try to pinch the tail end of the thermometer. Pay attention to check whether the thermometer is damaged, if the thermometer is damaged or broken, it will not be able to accurately show the correct body temperature.
Before using the thermometer, you can gently shake it a few times to let the temperature inside the thermometer soothe down, and then slowly hold it under the armpit and wait for about 10 minutes, paying attention to the mercury head that needs to be clamped under the armpit.
After the measurement, take out the thermometer from the end of the thermometer with your hands, remember not to shake the thermometer, and do not touch the metal head with your hands, otherwise it will cause inaccurate body temperature measurement.
Turning the thermometer slightly, I saw that there was a mercury bar inside, and the position of the mercury bar was the value of the body temperature. After using the thermometer, wipe it with a tampon ball dipped in imitation alcohol, so that it can be convenient for the next use.

Usage. 1. Before using the thermometer, the head of the thermometer should be disinfected with alcohol.
3. Then the display shows the temperature of the last side measurement as shown in Figure B (if the last measurement is, the well lasts for about 2 seconds.) The display may then display a "Flash" symbol as shown in Figure C, indicating that the thermometer is on standby. (If the room temperature is higher than 32, the thermometer will display the room temperature without showing as shown in the D figure, while the " " symbol keeps flashing).
4. Use a thermometer to measure body temperature. The temperature value displayed during the body temperature measurement gradually increases, while the " " symbol is constantly flashing.
5. When the body temperature rise rate is less than 0,1 within 16 seconds, the " symbol stops flashing, and the thermometer beeps for about 5 seconds, at this time, the thermometer is measured, and the displayed body temperature value can be read.
6. The thermometer has an automatic shutdown function, which will automatically shut down within 10 minutes after the end of the measurement. However, in order to prolong the battery life, it is recommended that the user press the power button to turn off the power after the measurement is over.
How to use the electronic thermometer.
The electronic thermometer can measure the ear temperature and the forehead temperature, and the ear temperature and forehead temperature measurement can be switched automatically by removing or closing the head cover. >>>More
Mercury thermometer is a common household thermometer, I believe many friends have used this thermometer, so, what is the use of mercury thermometer? What should I pay attention to when using a mercury thermometer? In fact, the use of mercury thermometer is relatively simple, and friends who want to know how to use mercury thermometer may wish to continue to look down. >>>More
Electronic thermometers use the physical parameters of certain substances, such as resistance, voltage, current, etc., to display the body temperature in the form of numbers. >>>More
The thermometer is used to measure the internal temperature of the human body, and the maximum range is usually only about 42 degrees, because this is basically the limit of the human body. The probability of exceeding this temperature is too low, and the change in the temperature in the human body is very small, so high accuracy is required, so the scale of the thermometer is often from about 34 to 42 degrees. >>>More
Hello, this is how the thermometer works.
Thermometers are also known as "medical thermometers". The working substance of the thermometer is mercury. Its vacuole volume is much larger than that of the thin tube above. >>>More
