Today, thermometers are absolutely in every home. And recently, the installation of room devices that measure temperature has become increasingly popular. In addition, do not forget about the mercury types of thermometers that measure the temperature of the human body. In general, the range of applications of these devices is very large. At the installation site, window, facade, water, room and even bath thermometers are distinguished. The types of devices in composition and design are less extensive. In addition to the classic mercury, there are infrared and electronic.
Outdoor mercury thermometers
Photo No. 1 shows us a standard window thermometer, which is probably in every apartment. Its main advantage is high measurement accuracy and low price. However, due to the use of a dangerous metal such as mercury, it is very dangerous to use it at home. And in order not to provoke depressurization of the device, it is necessary to protect it from various mechanical damages. However, for outdoor thermometers this is not as important as, for example, for household thermometers that measure the temperature of the human body. Regarding the scale, window thermometers are ways to display temperatures from -50 to +50 degrees Celsius. They are usually installed on a window frame or on glass. But that's not all devices.
Electronic thermometers
Types of external (window) devices are not limited to mercury thermometers. For example, an electronic device (indicated in the second photo) is very interesting. It has a small sensor, wire and a liquid crystal display.
This design allows you to control the outside temperature of the air without leaving the sofa. How does it work? Sensors that measure the temperature and transmit the signal through the wires to the display are displayed on the street. Thus, you can mount an electronic thermometer in almost any room to monitor its readings from there.
Water thermometers
The types of such devices are most often intended for bathing young children. Parents use them to control the temperature of the water while swimming, which is especially important for newborns. The scale of such devices is designed for readings from +10 to +50 degrees Celsius. However, some water thermometers are equipped with a red mark on a scale of 37 degrees Celsius. This indicator is just the most optimal for bathing children.
Also, some thermometers (types and varieties of mercury) can take the form of animals and cartoon characters, which attracts the attention of a baby who knows the world around him. However, remember that in the hands of a child such a thermometer can be damaged. This means that mercury can simply be depressurized, which is very dangerous for human health. Therefore, in this case, select devices that are most protected from mechanical damage or electronic. But the latter have a much greater cost than mercury thermometers. Thermometers
measuring the human body
temperature can be mercury, electronic and infrared. The third option is the safest and most accurate of its kind, so keep it in your medicine cabinet.
