The fact is that indeed, after the appearance of electronic thermometers, many mothers switched to this type of measuring device. It is safer relative to mercury, which can break, and mercury will expand. If an electronic thermometer breaks, respectively, there will be no consequences for the health of the whole family. Such a thermometer made of plastic and rubber is made, there is also a tip that is sensitive to fever.
The main advantages of electronic thermometers:
- Shockproof. Even if that thermometer falls on the floor, nothing will happen to him. This will not affect the accuracy of measurement.
- The speed of response. Many electronic thermometers notify that the temperature measured the sound signal. This usually happens in a minute. Although if you measure the temperature in the armpit, then the waiting time may increase to 3 minutes.
- There are additional functions in such thermometers. They remember the latest dimensions, and also have a backlighting display.
- There are interchangeable caps for hygiene.
Important: of the main disadvantages, the fact that such thermometers are less accurate than mercury. The usual error of such a thermometer is 0.2 to 0.3 degrees. In mercury, the error is no more than 0.1 degrees.
Thermometer for the newborn: which is better to choose?
Most often, young mothers acquire a thermometer in the form of a dummy for young children. Some models are designed to measure the temperature in the mouth. Moreover, measurements are made with a closed mouth. This greatly simplifies the temperature measurement process. Because many young children are quite restless, and it is quite difficult to withstand for 5 minutes with a thermometer in the axillary cavity. Therefore, a thermometer in the form of a nipple is suitable.
There is also a contactless thermometer that measures the temperature without contact with the body. The design is somewhat different from standard electronic ones. They measure the temperature in infrared radiation of the body.
Contactless thermometer: description, advantages and disadvantages
Now on the network there are new, interesting gadgets, which are called an infrared thermometer. This is a type of electronic thermometer, only for measuring temperature there is no need to apply it to the body.
Instructions:
- Measurement is carried out in the forehead and temple. You just need to direct the beam to this area
- Place the device at a distance of 3-5 cm from the surface of the body. In just a few seconds you will get the result
- Some high -quality thermometers of famous manufacturers give out the result in just one second
- Such thermometers are absolutely safe. At the same time, they will not disturb the child in any way, if he sleeps or watches cartoons
- Accordingly, you can measure the temperature anywhere and under any conditions
Many complain about the inaccuracy of such devices, due to the fact that the indications do not coincide with a mercury thermometer. Manufacturers claim that their device is high -precision and the error is not higher than that of conventional electronic thermometers. It is at 0.1-0.2 degrees. Young mothers are rarely acquired by this kind of thermometers due to their high cost. Indeed, their price is ten higher than the usual mercury thermometer. At the same time, due to not very good reviews on the Internet, few people decide to purchase such gadgets for their family.
But it is worth remembering that the measurement accuracy directly depends on how you observe the instructions for using the device, as well as how new batteries are in it. It is worth remembering that if the power sources, that is, batteries, sit down, then the thermometer can show a not entirely true temperature with a high error.
It is necessary that you always have spare batteries with you. Because an electronic thermometer can stop working at any time. Do not purchase products of Chinese manufacturers, as well as cheap thermometers. We advise you to buy only trusted products of well -known manufacturers who have passed certification and have an appropriate passport. Yes, indeed, electronic thermometers have a passport, they must be checked once a year.
Despite the presence of a large number of electronic thermometers, yet young mothers prefer mercury. This is due to their cheapness, as well as accuracy. Due to the fear of mercury poisoning, many still decide to purchase electronic models.
