Since childhood, we all used to measurebody temperature ordinary glass mercury thermometers. Their cost is low, they give fairly accurate readings, and besides, these thermometers have an unlimited service life, unless they are accidentally broken during shaking. Most likely, it is this reason that caused some to shift their attention to electronic thermometers, because one of their significant advantages is safety during use.
Such a thermometer is not terrible to drop, becauseit does not contain mercury, and if it suddenly breaks, then there will be no particular harm. For people with poor eyesight, this thing can also be a real find, because the electronic thermometer has a liquid crystal indicator that clearly shows the temperature figures, and now it’s not necessary to look at the indicators of the mercury column. Such wonderful measuring instruments are on sale in any drugstore.
However, such a thermometer has somefeatures The instruction says that after the signal is heard, you do not need to immediately watch the results, but rather hold for another two or three minutes. During this time, the readings may increase by half degrees or degrees. This feature is explained by the fact that the electronic thermometer has a too small sensor, which is in contact with the body is not enough. That is why the readings, which are obtained, turn out to be somewhat underestimated. In general, it is best to ignore the beep at all and keep the thermometer for three minutes (regardless of the manufacturer). Moreover, in most countries where these thermometers are released, the body temperature is measured orally or rectally, rather than under the arm, and, most likely, the meter was created with this in mind.
I would like to note that the highestThe accuracy of the measurements are certified devices, so the Chinese counterparts should be wary, not all of them have good quality. The principle of operation of the thermometer is based on changes in the electrical resistance of the conductor, followed by its conversion into numerical values, which are then displayed on the liquid crystal display. When determining the temperature, the device monitors its change, and when the temperature of the sensor ceases to change and stabilizes, the electronic thermometer will signal that the measurement is over.
We should also mention the thermometers for children.The device of some of them allows to measure the temperature of a child’s body even when he is sleeping. Enough to hold the device on the forehead of the child, from the temple to the temple. Other thermometers resemble a standard electronic thermometer in shape, but they have a bright, “toy” design. This electronic thermometer for children is safe for the baby, because it has a flexible tip and does not contain glass and mercury. In addition, many thermometers have a waterproof housing and a memory that stores the results of a previous measurement. There are also ear gauges. Most children's thermometers measure the temperature quickly enough, literally within 10-15 seconds. This is very convenient, given the restless nature of the kids.
Whatever electronic thermometer you choose,Remember that in order to obtain reliable results, you must strictly follow the instructions that are attached to the device. If this is not done, an increase in the error in the readings may occur, both upwards and downwards. If you rely on reviews of people using electronic thermometers, you can come to the conclusion that devices from different companies work differently and the error is also different, depending on how you measure the temperature. Often, to check the correctness of the result, the good old mercury thermometer is used.
