Correct use of ear thermometers, there are many expressions of the word correct?

What I want to say is:

If you use the earmuffs correctly, and if the earmuffs themselves are done well, the theoretical measurement accuracy can be ± 0.2 ° c.

The accuracy is pretty good, and it's worth spending a little more money on the convenience and speed.

Of course, a good ear warmer is one that minimizes misuse, even if you don't "use it right".

But as a user,braun digital ear thermometer, to get the most accurate measurements of an ear thermometer, it still has to be used correctly.

Returning to the title of the question, is the ear thermometer itself accurate or not, the answer I gave is: it is accurate enough!

Look at the hospitals now mostly use ear thermometers.

We can really develop the problem that needs to be concerned about how to use the ear thermometer to measure accurately.

How can I measure it accurately?

ambient temperature

Thermometers have a usable ambient temperature range, and if used outside the nominal range of ambient temperature, the measured body temperature may be inaccurate. This can be more important for ear thermometers, because the temperature range in which our general ear thermometers can be used will be smaller than that of contact electronic thermometers.

If the ambient temperature of use is not available, the general ear thermometer will go wrong.

My suggestion is to try to use the ear thermometer when the temperature is around 23~25℃. This social environment is the most accurate when measuring the temperature. It's like everyone who plays photography has heard the phrase "no dog head under f8". It means that the lens aperture is opened to f8, no matter how cheap the lens is, the imaging effect will not be bad. Similarly, no matter how cheap the ear thermometer is, the measurement error will not be too large at an ambient temperature of 23~25°C.

The temperature is measured with an ear thermometer in an environment with a temperature of 23~25°C, and the error is the smallest.

temperature balance

It is generally mentioned in the ear thermometer's manual that if the ear thermometer is used from one room to another, especially when the temperature of the two rooms is different, the ear thermometer needs to be placed for half an hour before use.

This is important for earmuffs. Since the temperature measurement principle of the ear thermometer requires the temperature of the temperature measurement head to be as stable as possible, the temperature change in the ring will cause the temperature of the temperature measurement head to be unstable, resulting in measurement errors.

There is another case of this measurement error, that is, when the ear thermometer probe is placed in the ear and comes into contact with the human body, the temperature of the ear thermometer probe will also be affected, resulting in measurement errors.

A good ear warmer generally optimizes the problem, for example, the probe is covered with metal, the continuous temperature measurement must be separated by a few seconds, etc., but it cannot solve the problem very well.
