Infrared thermometers work almost contactless. With these, an infrared sensor measures the radiation. The device converts the values into a temperature. Here, too, the readings are shown on a display.
The second group is made up of clinical thermometers, which enable an almost contactless measurement by means of infrared. This is divided into ear thermometers, where the measurement takes place in the ear, and forehead thermometers, which you point at the forehead to measure. There are also practical devices that come with an attachment that allows you to turn the ear thermometer into a forehead thermometer.
There are also basal thermometers. These measure the body's waking temperature to two decimal places. This variant is mainly used in the symptothermal method, a natural form of contraception in which the woman calculates her fertile days on the basis of her body temperature and the consistency of the cervical mucus. Accordingly, a basal thermometer can also be helpful when planning pregnancy.
If you use an electronic thermometer, the measurement time varies from device to device. You can find information on this in the manufacturer's instructions for use. Many models conveniently emit a signal tone when the measurement is finished.
With expansion thermometers you have to keep an eye on the time yourself. The measurement time depends on the measurement method - i.e. on which part of the body you are taking the temperature:
rectally - about four minutes
oral - about five minutes
axillary - eight to ten minutes
Infrared thermometers have the advantage that they measure the temperature within seconds. The measurement in the ear canal also provides good results. However, these can be falsified, for example, by a middle ear infection. Wrong measurements sometimes occur with forehead thermometers.
Rectal measurement is usually unpleasant for the little ones and requires some parental skill. If your baby is older than three months, you can also use an ear thermometer. The quick measurement saves both children and parents some stress. With a forehead thermometer, you can take a temperature even when your baby is asleep, sometimes within just one second. However, the measuring accuracy is lower than with the digital thermometer.
There are also so-called pacifier thermometers especially for babies. As the name suggests, these are pacifiers with an integrated thermometer. In theory, this measures the body temperature while your child sucks on it. In practice, however, this does not work so well, because the pacifier does not reach far enough into the mouth and babies usually do not keep it long enough in the closed mouth.
Ear thermometers usually have disposable protective caps that you change after each measurement. If not, treat them carefully with rubbing alcohol.
You can find detailed information about the type of batteries and how many batteries each model requires in the product descriptions or in the manufacturer's instructions.
You can put digital and infrared thermometers in the residual waste. However, it is more exemplary if you dispose of them as electrical waste.
Empty batteries have no place in household waste. Dispose of them in the designated collection boxes in a supermarket or drugstore near you.
