The Purpose of the Thermometer

We all know that a thermometer is used for temperature measurement ..

So, in accordance with this, the thermometers are used as:

  • Medical Instrument as it is designed to measure the temperature of the patient’s body. On sale you can find devices intended for adults and baby thermometers . The latter are designed to measure temperature in babies, do not contain mercury and use the latest technology to work quickly without any discomfort for babies. Some models are made in the form of a nipple , so they are suitable even for babies.

Let’s take a closer look at medical thermometers. Before buying, it is worth knowing that the temperature can be determined by several methods.
This is not only the traditional axillary measurement but also the frontal or ear models. Thanks to the latest developments in technology, the temperature measurement process has been facilitated or shall we say “leveled-up”. 

Which Thermometer Technology is best?

It can be noted that modern developments have practically replaced the old mercury thermometers, and their place was taken by:

Electronic Thermometer 

Temperature measurement is carried out using special thermistors, the resistance of which directly depends on the temperature of the environment in which they are located. The readings obtained are displayed on the display located at the opposite end of the thermometer. With this thermometer, you can measure the temperature in all familiar places. The average measurement time is three minutes, but to obtain more reliable data, this time should be increased to 5-8 minutes. 

Among the main and additional functions of such a thermometer, it is worth noting:

  • The presence of a sound signal that will notify about the end of the measurement.
  • The backlight will make reading comfortable even in the dark.
  • Memory will help you compare previous readings with new ones.
  • Some models are equipped with the ability to change the measurement scale from Celsius to Fahrenheit.
  • The waterproof case makes it possible to take measurements in water and makes the thermometer immune to sweat.
  • The flexible measuring tip will make the use of the thermometer comfortable even for children.

Infrared Thermometer 

Such thermometers are still a novelty but have already gained popularity for the possibility of contactless temperature measurement. The temperature is measured with a very sensitive infrared sensor. To do this, you just need to bring the thermometer close to the body, and after 5-30 seconds it will display the body temperature. These models are especially popular with parents with small children, especially babies. 

Such thermometers can be equipped with:

  • Sound signal about the end of measurement and temperature rise;
  • Memory for the last few measurements;
  • Waterproof housing , which will increase the service life and allow disinfection.
