Today, there are thermometers in absolutely every home. Moreover, in recent years, 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 application of these devices is very large. According to the place of installation, window, facade, water, room and even bath thermometers are distinguished. Types of devices in composition and design are less extensive. In addition to the classic mercury, there are infrared and electronic.
Outdoor mercury types of 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 such a dangerous metal 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 ones that measure temperature.human body. As for the scale, window thermometers can show temperatures from -50 to +50 degrees Celsius. They are usually installed on the window frame or on the glass. But that's not all devices.
Electronic thermometers
Types of outdoor (window) devices are not limited to mercury thermometers. For example, an electronic device is very interesting (indicated in the second photo). It has a small sensor, wire and liquid crystal display.
This design allows you to control the outside temperature without leaving the sofa. How does it work? Sensors are brought out into the street that measure the temperature and transmit a signal via wires to the display. Thus, you can mount an electronic thermometer in almost any room in order to monitor its readings from there.
Water thermometers
Types of such devices are most often intended for bathing young children. Parents use them to control the temperature of the water during bathing, which is especially important for newborns. The scale of such devices is designed for readings from +10 to +50 degrees Celsius. At the same time, some water thermometers are supplied 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 be shaped like little animals and cartoon characters, which attracts the attention of a baby who is learning about the world around him. However, remember that inthe hands of a child, such a thermometer may be damaged. And this means that mercury can simply depressurize, which is very dangerous for human he alth. Therefore, in this case, select devices that are maximally protected from mechanical damage or electronic. But the latter are much more expensive than mercury thermometers. Thermometers that measure the temperature of the human body can be mercury, electronic and infrared. The third option is the safest and most accurate of its kind, so keep it in your first aid kit.
