Non-contact thermometer, or pyrometer, is a device for measuring body temperature and other objects. The history of the creation of this device, its types and principle of operation, we will consider below.
Main purpose
non-contact thermometer
Non-contact thermometer is actively used for remote or remote determination of body temperature, objects in the housing and communal services, industry, everyday life, as well as at various enterprises (in steel and oil refining areas). The basic principle of operation of such a device is based on a kind of measurement of the heat power of an object in the ranges of visible light or infrared radiation.
The non-contact thermometer is an ideal tool for safely measuring the temperatures of especially hot objects. This fact makes them almost indispensable for providing the necessary control in cases where physical interaction with an object is impossible due to its extremely high temperatures.
It should also be noted that today there are such models of contactlessthermometers intended for medical purposes. So, with a pyrometer, you can remotely measure the body temperature of a child or an adult during his sleep, while not disturbing the patient in any way.

History of Creation
The very first non-contact thermometer was invented by Pieter van Muschenbroek. Initially, the term "pyrometer" was used only in relation to those instruments that were intended to measure visual temperature, that is, by the degree of brightness and color of a hot object. Today, the meaning of this word is somewhat expanded. For example, some types of non-contact thermometers are more appropriately called infrared radiometers, because they measure quite low temperatures. By the way, similar medical devices originated from industrial pyrometers.
Types of pyrometers
The non-contact thermometer, reviews of which are only positive, is divided into the following types:
Optical. Such pyrometers allow you to visually determine the exact temperature of a heated human body. This is done by instantly comparing its shade with the color of the thread (reference).
Radiation. These non-contact thermometers determine the temperature using the converted radiant power (thermal).
Color, Spectral or Multispectral. The presented pyrometers draw conclusions about the temperature of an object by comparing its thermal radiation in different spectra.

The advantages of such partings for measuring body temperature include:
ergonomic and beautiful design (quite comfortable in the hand);
possibility to measure the temperature of any other surface;
small sizes (the length of the device is only 15 centimeters);
accurate forehead temperature measurements;
opportunity to choose ℉ or ℃;
easy setting of a specific temperature value at which the buzzer will sound;
memory for the last 32 measurements;
LCD backlight.
It is also worth noting that a non-contact thermometer, the price of which varies between 1, 2-3 thousand rubles, can automatically hold data and turn off the power.
Body temperature is one of the main indicators of human he alth. Its deviation from the norm indicates the presence of the disease. Therefore, it is important to know how to set the thermometer correctly so that the result is the most accurate
