Is it possible that the mercury thermometer is out of order, what is going on if the mercury thermom

Possible. Judge mercury thermometer.

Whether it is damaged or not can be used to observe the number method. The easiest and most straightforward way is to observe the readings on the thermometer and use the thermometer to measure the temperature of different objects. Mercury thermometer.

Sometimes there is a common failure, if the tip of the mercury thermometer is damaged or there is a leakage of steam during the production process, the liquid mercury can be raised normally or the liquid mercury can not return to the top of the electronic thermometer, which will immediately cause the accurate measurement data information to be inaccurate or significantly biased. In addition, mercury thermometers are sensitive and can be easily damaged after bumps.

How to know if the mercury thermometer is broken or not.

1. Observe the large number method: a very simple and immediate way is to observe the reading value on the electronic thermometer. If a thermometer is used to measure the temperature of different blocks, if the temperature value does not change, this indicates that the electronic thermometer is broken.

2. Water detection: you can put the electronic thermometer in the sink, and put some water in it before the electronic thermometer, if there is a bubble, it means that the electronic thermometer is leaking.

3. Immediate observation: You can immediately observe the surface of the electronic thermometer, whether there are gaps or scratched areas.

Mercury thermometers are generally unlikely to fail, because the mercury in a confined space is not disturbed in any way, and the physical properties of thermal expansion and contraction determine that the mercury thermometer cannot fail.

Summary. Hello dear and happy to answer for you. Unresponsive use of mercury thermometers may be due to incorrect use, or damage to the thermometer, as well as changes in mercury columns that are not reasonably observed.

First, the mercury thermometer can be thrown below, and then the metal end can be clamped to the armpit for more than five minutes, and the body temperature can be observed. Usually, the thermometer should be slightly flipped to find the position where the mercury column stays, that is, the position where the body temperature is measured, and the tilt angle must be slightly flipped to observe the mercury column, which can be understood by comparing the scale on the thermometer.

Usually the thermometer should be slightly flipped to find the position where the mercury column stays, that is, the position where the body temperature is measured by Gai Suixiao, and the angle of inclination must be slightly flipped to observe the core of the mercury column, which can be understood by comparing the scale on the thermometer.

It may be that there is a problem with the quality of the mercury thermometer itself, and it is possible that the mercury column is not good enough to rise and achieve the purpose of measuring body temperature. In addition, when we measure body temperature, if the mercury thermometer cannot be well bonded to our swim section, it is also regretted that it may lead to inaccurate body temperature we measure, and the mercury thermometer will fail.

Dear, I'm glad to answer for you: the mercury thermometer can't be thrown off is generally due to the failure of the thermometer, and the reason for the failure is generally the mercury column into the gas, or the glass pipe in the thermometer is not used all year round to form a plug, blocking the thermometer, so it fails. In this case, just change a mercury thermometer.

The mercury thermometer will rise after being heated, but the temperature drop will not automatically recover, and it needs to be thrown off manually, and it will definitely not rise if it is higher than the body temperature. It is recommended that you throw the mercury column off before taking the measurement. In addition to mercury thermometers, electronic thermometers can also be used.

Because the electronic thermometer is not affected by mercury mercury, it is not affected by the embolus that forms an embolus to block the belly after the liquid expands, so it is also very convenient to use, and the cost is not expensive, suitable for the public, and the reading of the electronic thermometer is particularly close to the people and humanized, which is convenient for people with poor eyesight or who do not know much about the reading of the mercury meter.

1. Observe the number method. The easiest and most straightforward way to do this is to look at the readings on the thermometer. If you use a thermometer to measure the temperature of different objects, if you find that the temperature value has not changed, it means that the thermometer has been damaged.

2. Water test. You can put the thermometer in the basin, and put some water in the thermometer to cover the thermometer, if there are bubbles, it means that the thermometer is leaking.

3. Direct observation method. You can directly observe the appearance of the thermometer and see if there are cracks or scratches.

Mercury thermometer is a tool that we often use to determine body temperature, and it is currently the most practical and accurate thermometer.

How to use a liquid thermometer:

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. When measuring, make the glass bubble of the thermometer fully contact with the liquid to be measured (to be immersed in the liquid to be measured).

3. Wait for the indication to stabilize before reading.

4. When reading, the glass bubble of the thermometer should be left in the liquid to be measured, and the reading cannot be taken out.

The mercury thermometer is measured by the principle of thermal expansion and contraction, and the nuclear return structure is simple and not easy to break, but it is necessary not to use it beyond the range, and the range measured by the thermometer is 35-42 degrees. In addition, the mercury thermometer is easily broken or damaged, if the mercury thermometer is broken and leaking, and the internal mercury is insufficient, the body temperature will not reach the true scale. How to determine if the thermometer is damaged:

First, you can observe whether the surface of the thermometer is damaged. 2. When measuring body temperature, pay attention to observe whether the body temperature can rise and whether it is in line with your body temperature. 3. You can also put the thermometer in the basin, put some water in it and not pass the thermometer, if there are bubbles in the Suishi wheel, it means that the thermometer is leaking.

Hello dear! The mercury thermometer does not show up when used for the first time, there may be improper use, or damage to the thermometer, and there is no reasonable observation of changes in the mercury column. First, the mercury thermometer can be thrown below, and then the metal end can be clamped to the armpit for more than five minutes, and the temperature can be observed by taking it out, usually turning it slightly.

Dear, if the mercury thermometer is damaged, there is leakage, and the mercury inside is insufficient, the measured body temperature will not reach the real scale, so before use, you should observe whether the surface of the thermometer is damaged, pay attention to whether the body temperature can rise, whether it is in line with your own body temperature, you can also put the thermometer in the basin, if there are bubbles, it means that the thermometer is leaking; Whether the use is correct, the mercury thermometer must be shaken a few times before use, so that the mercury returns to its original position and then measures the morning temperature, so that it is accurate, if it is to measure the temperature of the armpit, you must first wipe the sweat from the armpit, put the mercury end of the thermometer under the armpit, and clamp the thermometer with the upper arm.

Summary. If the mercury of the newly bought thermometer can't be shaken off, you can use alcohol to wipe the end of the mercury column, wait for a minute or two, the mercury will drop to the normal position, or put the temperature into the ice water, if the mercury still does not change, then it is considered that the thermometer quality is abnormal. Generally speaking, the mercury thermometer can easily be thrown below 35 degrees, if the mercury of the newly bought thermometer cannot be shaken, considering that the thermometer has quality problems and needs to be replaced.

When using a mercury thermometer to measure body temperature, it is necessary to throw the mercury column below 35 degrees before the measurement, so as not to affect the measurement results.

Dear, glad to answer for you you can try the following methods:

Wipe the end of the mercury column with alcohol, or use a small amount of wine Kai to do fine immersion at the end of the Zhaoheng soaking mercury column, wait for 1-2 minutes to guess the clock, and the mercury column will drop to the normal position. Put it in ice water or alcohol, and after a while the mercury will run down.

The newly bought thermometer mercury can't be shaken off, you can use alcohol to wipe the end of the mercury column, wait for a minute or two, the mercury will change to drop to a normal position, or put the temperature into the ice water, if the mercury still hasn't changed, then it is considered to be caused by the abnormal quality of the thermometer. Generally speaking, the mercury thermometer can be thrown below 35 degrees, if the mercury of the newly bought thermometer cannot be shaken down, considering that the thermometer has quality problems and needs to be replaced.
