The correct way to use the thermometer How to look at the mercury thermometer

The correct way to measure body temperature with a mercury thermometer is as follows:

Wash your hands, pinch the glass end of the thermometer, and shake the thermometer below 35.

Place the mercury end on the top of the armpit and clamp it, measure it for 10 minutes, and take out the reading.

When reading the value of the thermometer, the following steps should be followed:

Hold the glass end of the thermometer with your hand, the end away from the mercury column, so that your eyes are at the same level as the thermometer.

Slowly turn the thermometer and read the corresponding temperature value when you see a thick column of mercury from the front.

It is important to note that:

When using a mercury thermometer, it should be handled with care and placed in a protective case to avoid damage.

If there is a damaged mercury thermometer, it should be cleaned in time and the doors and windows should be opened for ventilation in time.

Wash your hands, pinch the glass end of the thermometer, shake the power of the thermometer below 35, then put the mercury end on the top of the armpit and clamp it, measure it for 10 minutes and take out the reading.

Correct Reading Method:

Hold the glass end of the thermometer with your hand, that is, the end away from the mercury column, so that your eyes are at the same level as the thermometer, and then slowly turn the thermometer to read the corresponding temperature value when you see the thick mercury column from the front. Be careful not to touch the mercury end of the thermometer with your hands, otherwise it will affect the mercury column reading and cause inaccurate measurement.

How to save it. When using a mercury thermometer, handle it with care and put it in a protective case to avoid damage. If damaged, the mercury spilled from the thermometer can turn into mercury vapor if not properly disposed of, causing inhalation poisoning.

If there are more than one person in the household, it should be disinfected and rotated. The correct disinfection step is to rinse the thermometer with clean water after measuring the body temperature, shake the water dry as much as possible, then soak the mercury end down, soak it in 75% medical alcohol for 3-5 minutes, dry it, and put it in the cleaning box for next use.

It seems to be thrown below the scale before use, and then put it under the armpit for about 5 minutes, and take it out to see if there is a fever.

The working principle of the thermometer and the thermometer is the same, both of which apply the properties of some liquid heated expansion However, because the working requirements of the two are not the same, there are some differences in the structure Mainly there is a small inflection at the lower end of the thermometer near the liquid bubble When the body temperature is measured, when it is taken out of the clothes, the mercury becomes cold and shrinks and breaks at the inflection, and the mercury at the upper end cannot flow back, so that the value of the thermometer will stay at the temperature value when measuring the body temperature

The difference in the use method is that the thermometer can be taken out of the object to be measured when reading, while the thermometer cannot do this, otherwise the value will change and be inaccurate

Kiss Mercury thermometer is a common temperature measurement tool, and accurate temperature values can be obtained when used correctly. The correct way to use a mercury thermometer to get cracked down:1

Before use, place the thermometer in a horizontal position to ensure that the mercury column is high guess square under the scale line. 2.Insert the thermometer into the liquid to be measured, making sure the thermometer is completely immersed in the liquid, but do not touch the bottom of the container.

3.Wait for a while until the thermometer reading is stable. It usually takes 1-2 minutes to wait.

4.Read the scale value on the thermometer. The number above the mercury column indicates degrees Celsius, and the number below indicates degrees Fahrenheit.

5.After use, take out the thermometer and shake it gently a few times to bring the mercury column back to the bottom. It should be noted that the mercury thermometer is an item that is easy to be broken and easily contaminated, and it needs to be handled with care when using it to avoid falling or breaking.

After use, the thermometer should be cleaned and kept in a safe place. If the thermometer is damaged, it should be discontinued immediately and disposed of in accordance with local environmental regulations.
