Today thermometers have absolutely every house.And in recent years it has become increasingly popular Setting the room temperature measuring device.Also, do not forget about the kinds of mercury thermometers to measure the temperature of the human body.Generally, the range of application of these devices is very high.On-site distinguished window, facade, water, and even the bath room thermometer.Types of devices on the composition and structure less extensive.In addition to traditional mercury, there are infrared and electronic.
External mercury thermometers kinds
Picture number 1 shows us the standard window thermometer, which is probably in every apartment.Its main advantage is the high accuracy of measurement and a small price.However, due to the use of such hazardous metals such as mercury, use it at home is very dangerous.And in order not to provoke a depressurization device, it is necessary to protect it from a variety of mechanical damage.However, for outdoor thermometers it is not so important, as, for example, for home, measure the temperature of the human body.As for the scale, window thermometers ways to show the temperature range from -50 to +50 degrees Celsius.They are usually installed on a window frame or a glass.But that's not all devices.
Electronic thermometers
types of outdoor (window) devices are not limited to mercury thermometer.For example, very interesting is the electronic device (shown in the second photo).It has a small gauge, the wire and the liquid crystal display.This design allows you to control the temperature of the outside air without leaving the couch.How does it work?On the outside output sensors that measure temperature and transmit a signal to the display through wires.Thus, the electronic thermometer can be mounted almost anywhere in the room to watch out for his testimony.
Water thermometers
Types of such devices often are meant for bathing small children.Parents use them to control the temperature of the water while swimming, which is especially important for newborns.The scale of such devices designed to testimony from +10 to +50 degrees Celsius.However, some water thermometer supplied with the red mark on the scale of 37 degrees Celsius.This figure is just the most appropriate for children.Also, some thermometers (mercury species and varieties) may be in the form of little animals and cartoon characters that attracted the attention of the baby, knowing the world.However, remember that in the hands of a child of the thermometer may be damaged.This means that the mercury could simply develop leaks, which is very dangerous for human health.Therefore, in this case matches a device maximally protected from mechanical damage or electronic.But the latter have a much greater value than mercury thermometers.Thermometers that measure the temperature of the human body may be mercury, electronic and infrared.The third option is the most secure and accurate in its own way, so keep your home medicine cabinet is his.
