What is a thermometer? a brief description of

Of course, everyone knows what a thermometer is. This is a special device for measuring any medium. Let us consider in more detail its variants and possible ways of using it. Also, the article gives recommendations on how to choose the most suitable thermometer for a child. And for the curious, information on compliance with certain conditions for the storage of medicinal products is given.

What is a thermometer? Its varieties

When creating the most ordinary thermometers, the properties of mercury are used to expand under the influence of temperature changes. In addition to this species, there are other thermometers.

Electronic device

Inside it are special materials, when heated, the resistance of the electric current changes. The result of the readings are the numbers on the scoreboard. To date, an electronic thermometer is the most popular and accurate of all instruments measuring the changes of any environment.

Infrared device

This device can measure temperature without direct contact. For example, it will be enough simply to apply the thermometer to the forehead of the patient not for a few seconds, and he will turn off at the right time and notify the result. But, unfortunately, the measurements obtained may not be accurate enough. It is more convenient to use it in rare cases, for example, on the road. And at the usual time to operate traditional instruments.

Which children's thermometer is most convenient and practical in application?

All parents, of course, have this device in their medicine cabinet. And, unfortunately, sooner or later the baby will know what a thermometer is. And the sick children differ in their majority capriciousness and not quite an active desire to get acquainted with new subjects. Therefore, when choosing a thermometer for a child, one must take into account its possible unpredictable reaction. Imagine that a crumb can accidentally throw an unfamiliar thing and smash it. In addition, he simply does not want to sit for a long time without moving to determine the heat level. And for all the explanations of what a thermometer is and why it is used, it will react with protests. What are the requirements for a children's thermometer? Since mercury devices are dangerous to use, it is better to choose the more practical electronic devices. They are most convenient and accurate in measurements, unlike conventional glass cones or infrared indicators. By the way, for the youngest thermometers are available in the form of a special nipple.

How does a wet thermometer work?

Once we talked about the diseases and the need for their treatment, let's talk about medicines. It turns out that for storing many of them you need to observe a certain environment of ambient air. And this is not only the right temperature, not exceeding the limiting lower and higher values, but also the relative humidity of the room. At home, such necessary conditions do not necessarily have to be respected, since drugs are not stored for long, because they are mostly purchased as needed. What can not be said about pharmacies. Then a special moist air thermometer - psychrometer - comes to the rescue. It looks like a plastic box with two scales on the front wall. On the reverse side of the device is a cone with water, into which one end of the tissue, which comes from the inside, is lowered. Taking the readings from both available thermometers on the scoreboard, the humidity level is calculated on a special scale.

As you can see the range of application of such, at first glance, a simple device, like a thermometer, is very wide. About what other purposes it can be used for, we'll cover in another article.
