How to Use a Digital Thermometer

Measuring one's temperature is easiest with a digital thermometer. This device displays the temperature very accurately and is also convenient to read. Modern digital thermometers often have a memory function to save the temperature information, and can even connect to a computer. Digital thermometers can measure temperatures from various spots on the body, depending on the specific need for taking the temperature in the first place. Somewhat different instructions apply for different kinds of measuring, and it is important to learn them so as to use the device properly. Digital thermometers are available in many high street stores, while online sites, such as eBay, may also offer deals on these and other health-related items.

Preparing for Measuring with a Digital Thermometer

Before starting to measure, it is essential to read the instructions thoroughly in order to know how the thermometer alerts once the reading is complete. The screen should be clear of any old readings before starting. Should the device come with a plastic sleeve or covering, this needs to be on during the measuring process and discarded after use. The thermometer may also require some cleaning before one puts it back into its casing.

Measuring Temperatures from Different Places

There are several areas on the body where one can take the temperature. The average normal body temperature is about 37 degrees C. There are several factors that may influence the normal temperature, such as the time of the day (temperature is generally higher in the evening) and age (children have higher temperatures). Strong emotions, workouts, certain medicines, teething, menstruating, and eating can also affect temperature. The following table compares the average temperatures on different parts of the body.

Part of the Body

Average Normal Temperature

Mouth

37 degrees C

Rectum

37.3 to 37.6 C

Ear

37.3 to 37.6 C

Armpit

36.4 to 36.7 C

In the case of children, the most accurate reading usually comes from the rectal measurement. A reading from around one degree to 1.5 degrees above the normal temperature indicates a fever.

Measuring Rectal Temperature

For measuring rectal temperature, the thermometer needs lubrication, such as petroleum jelly. The person lays on the back, lifting the thighs. The thermometer goes about 1.3 to 2.5 centimetres into the rectum and one should stop the insertion process in the case of any resistance.

Measuring Oral Temperature

The tip of the thermometer goes under the tongue for measuring. The lips need to remain closed. At least half an hour must pass after eating or drinking. This method is not suitable if the person is not able to breathe through the nose.

Measuring Armpit Temperature

The thermometer goes under the armpit to measure the axillary temperature. It is essential to ensure that it touches the skin, not the clothes. The thermometer has to stay tightly in place until it signals. It is best to keep the arm close to the body to hold the thermometer and prevent it from slipping.

Measuring Ear Temperature

For measuring the ear temperature, or tympanic temperature, the thermometer goes gently inside the ear. The accompanying instructions should detail how to properly insert the device into the ear canal and how far it can go. The measurer should hold the thermometer tightly in place during the process.

Calibrating a Digital Thermometer

Any digital thermometer requires a calibration every once in awhile in order to ensure accurate readings. Thermometers also need calibration before the very first measurement, after dropping them on the floor, and for measuring extreme temperatures. There are two tests for checking whether the thermometer requires calibration: putting it into an ice-filled glass, or putting it into boiling water. In the former case, if it reads 0 C, then it is fine. In the latter case, it does not need calibration if it reads 100 C. Otherwise, the adjuster on it needs turning until it reaches the correct reading. Pressing the reset button may also help.

How to Buy a Digital Thermometer on eBay

eBay sellers offer a wide range of deals on medical and wellness products, including digital thermometers. You can find the thermometer you need by using the search box. If you require a thermometer for measuring the temperature from a specific part of the body, you can look for a thermometer that is especially for this purpose. For instance, you can search for an axillary, oral, or tympanic device. You can also find these specifications in the detailed item listings. Before you start taking the temperature, you should always clean the thermometer. Be sure that you also calibrate the thermometer occasionally in order to ensure accurate readings, especially if you drop it onto the floor.
