The market for medical devices has long been filled with electronic thermometers, which replaced the mercury ones. But is everyone aware of the principle of operation of these devices? And can they be trusted?
The principle of operation that distinguishes an electronic thermometer from a mercury one is based on the readings of a miniature sensor that responds to the slightest changes in body temperature. For the most accurate result, the device should be as close to the body as possible. Any effect of the surrounding space may distort its readings.
The electronic thermometer is equipped with a plastic housing, but this does not mean that it has shockproof or waterproof properties, because the microcircuit of the device may suffer from such effects. It is also necessary to protect the device from direct sunlight and vibration, as this can cause the failure of the electronic mechanism, which will lead to serious damage to the device.
But the electronic thermometer has its own huge advantages:
1. It is equipped with a digital screen.
2. Each electronic thermometer is equipped with an audible signal. The device makes a sound when turned on, which confirms its performance. At the end of the temperature measurement , a signal also sounds - this means that the procedure is completed.
3. The memory of the latest digital technology stores the testimony of several recent examinations. This allows you to control the slightest deviations in the results.
4. Plastic devices are safe for independent use by their children. You can not be afraid that the thermometer will break.
5. The thermometer turns off automatically if there is no need for its further application.
6. The electronic device is powered by batteries. It is enough to replace the old power with a new one, after which you can use the device for several more years. Even if the device is disposable (in the sense that the manufacturer does not provide for the replacement of batteries), it will still have a life of up to several thousand hours.
7. Some models of electronic thermometers are equipped with a backlight, which allows them to operate at night without turning on electricity.
8. The electronic children's thermometer is equipped with a flexible tip, which makes it possible to measure the temperature in a rectal or oral way.
9. Some manufacturers equipped their products with protective covers, which saves the case from mechanical damage, and therefore the issue of storage disappears by itself.
10. All electronic thermometers have a special button to turn on. Thanks to her, you do not need to shake the thermometer to throw off the last temperature reading.
The electronic counterparts of mercury thermometers are safer for use in the modern world. For proper and accurate use, you must carefully study the instructions. And finally - information for thought. Almost all countries of the world today have abandoned the use of mercury thermometers due to the presence of such a toxic substance in their composition. Health is more important.
