Forehead thermometer, clinical thermometer, ear thermometer which is better?

Some netizens said:
I think the mercury thermometer is the most accurate!
If we actually use mercury thermometers,
What will happen to it?
Mercury thermometer VS forehead thermometer
The security guard will say:
", please take off your gloves, friends raise your hands,
Tell me the temperature after 5 minutes. "
So you messed up in the wind
Must be thinking like this:
After the epidemic, I promise I will not beat you!
Will appear at the door of the company that morning
A "long dragon" of a clinical thermometer,
Gather a crowd to take body temperature? Looks unreliable!
At the same time, because the mercury thermometer touches the skin or mucous membrane of the human body,
It is also more prone to cross-infection.
This round, the forehead gun will be a sneak peek!

Some netizens said:
Ear thermometers will be used in the triage of the hospital, right?
Okay, let's use an ear thermometer.
Ear thermometer VS forehead thermometer
An ear thermometer is a thermometer that goes into the ear hole to measure the temperature of the tympanic membrane.
The measured temperature is also reasonable.
In actual operation,
The ear thermometer will inevitably touch narrow ear holes.
If you want to avoid contact,
If you choose to buy an ear thermometer, you can enjoy a happy protective film.
However, this will greatly improve,
A lot of work has been added.
In this round, the Forehead Gun won again!
So, no matter from simple operation,
The economic cost is to avoid cross-infection.
Forehead thermometers are the most suitable choice.
Rumor: If the forehead is not accurate, can the test be accurate?
In winter, people who come from the outdoor temperature, or people who are automatically or in a car (the temperature in the car may continue), due to temperature changes and other reasons, may cause the forehead thermometer to read an appetite that does not match the actual body temperature.
At that time, the measurement of the wound covered by the skin may be more detailed.
However, the forehead thermometer was originally designed to measure the forehead, and it is actually calculated based on the difference between the skin temperature of the head surface and the temperature of the human body. Therefore, it is best to use a forehead thermometer to measure the head.
If you really want the forehead spear to grow,
Then you can roll up your sleeves!
Please measure the swelling part of the skin (left and right hand) that is covered by human skin and not exposed to the air, and measure the distance at 6 to 8 from the swelling measurement. The temperature obtained is closer to the real temperature of the human body.

Tips: How to measure the accurate temperature with a forehead gun
It is possible to use a combination of multiple measurement, multiple measurement and comparison methods. Several times, take the average result.
The operation steps are as follows:
Personnel first make sure that their body temperature is normal (for example, they have measured their own body temperature with a mercury thermometer); then they use a forehead thermometer to measure their own temperature. If the emotion is measured, it is 36°C. At this time, if the person under test takes multiple measurements, If the body temperature is significantly higher than 36°C, further observation is necessary.
, I think of it, there is a legend on the Internet that the body temperature hurts the eyes for the last time, which may cause eternal harm.
The principle of temperature measurement is to receive the infrared rays emitted by the object, and it will not actively detect the object by infrared, so don't worry too much. If you feel uncomfortable, just close your eyes.
