Woman's Day prepared a review of thermometers, revealing the merits and demerits of each.

Mercury thermometer

Today in the pharmacy you will find different types ofthermometers. In place of the usual mercury came a lot of new products, but it still remains the leader in sales. Perhaps, because it is still considered the most accurate (the error of a mercury thermometer is not more than 0.1 degrees) and simple in operation. But still it is not the most convenient and safe option for children:

• mercury thermometer is dangerous for the child: its design is fragile, the thermometer is easy to break and diffuse mercury, which is known to be toxic;
• To measure a temperature of a body to children such a thermometer it is possible only under a mouse. Oral and rectal variants are excluded, as they can damage the device, which in turn will harm the child;
• so that the result is as accurate as possible, you need to wait 7-10 minutes. Keep the child with a thermometer under the arm for so long is extremely difficult.

Electronic thermometer

A digital thermometer has long won loveparents, because it is very easy to use and safe for young children. It determines the temperature of the body due to a special sensor built-in, and the result displays digitally on the screen. Such thermometers have additional functions, such as memorization of the last result, warning sound signal, waterproof case, interchangeable tips. For children electronic thermometers are produced in a cheerful design, in the form of animals or toon, bright color. Such a thermometer can be purchased not only in the pharmacy, but in any children's store. The main benefits include:

• speed measurement: only 30-60 seconds, and the result is already on the screen;
• safe even for infants, since it does not containmercury. You can measure it in three ways (the thermometer has a flexible tip), but remember that in different parts of the body the temperature is always different. The rectal temperature is 0.5 degrees greater than the oral temperature and almost a degree higher than the axillary temperature;
• The temperature can be measured in the dark, on some grades there is a highlight.

But the digital meter has its drawbacks:

• inaccuracy of measurement (0,5 degrees towards the underestimation). Therefore, it is better to use it to find out if there is any heat at all, and for a more accurate result use another device;
• the need to change the batteries, the charge of which can end at the most inopportune moment, so stock up an extra set;
• short-lived: quickly breaks down, especially if it falls into children's hands.
