A thermometer is a very small object, but it is a household necessity. When you have a headache or a cold, you always need to measure whether you have a fever or not to decide whether to take antipyretic medicine, especially if you have a baby. Although the use of thermometers in everyday life has become very common, but for first-time users, there is still the problem of not knowing how to see the thermometer. How long to measure the thermometer For different thermometers, the time needed to measure varies. The general mercury thermometer measurement time is 5 to 10 minutes; electronic thermometer use time is 1 minute; ear temperature thermometer use time is only a few seconds. How to see the thermometer Although the use of thermometers in daily life has been very common, but for the first time use of people, there is still do not know how to see the thermometer problem. So next we will introduce how to see the thermometer. Hold the end of the thermometer in one hand, that is, away from the end of the mercury column, so that the eye and the thermometer to maintain the same level, and then slowly turn the thermometer, from the front to see a very thick column of mercury can be read out the corresponding temperature value. Read the number of attention should never touch the mercury end of the thermometer with your hand, which will affect the mercury column and cause inaccurate measurement. The use of thermometers The main thermometers on the market are mercury thermometers, electronic thermometers and infrared ear thermometers. Then we will introduce you to the use of the three thermometers. Electronic thermometer use: electronic thermometer can be ear temperature and forehead temperature measurement, ear temperature and forehead temperature measurement of the switch, can be removed or cover the head cover the way to automatically switch. Electronic thermometer usage of the ear temperature measurement – remove the head cover, press the scan button to start, the measurement probe into the ear canal, press the scan once, hear the “wow” sound, the measurement is complete. Electronic thermometer usage of the forehead temperature measurement – cover the head, press the scan button to start, the measurement probe flat against one end of the temple, press and hold the scan button, move along the forehead to the other end of the temple. After hearing the “wow” sound, the measurement is complete. Mercury thermometer use: If the mercury thermometer is not used alone, before the amount of alcohol cotton (no alcohol cotton can be cleaned with cold water) wipe over and wipe dry. The mercury in the traditional mercury thermometer will be dumped to below 35 degrees. Mercury thermometer placed in the armpit clamping, note that the mercury needs to be in the middle of the armpit. Do not let go of the arm and do not move around. After measuring, take out the mercury thermometer to see the results, and then do the cleaning. Infrared ear thermometer use: In order to avoid the accuracy of the ear thermometer due to the external environment of too cold or too hot, so the ear thermometer must be placed in the general environment for at least 30 minutes before use, in order to avoid incorrect measurement results. The subject should be at room temperature for a minimum of 20 minutes to allow the body temperature to equilibrate. Avoid wet ears and keep ears clean before use. No obstructions or excessive ear wax buildup in the ear is necessary to get an accurate temperature measurement. After strenuous exercise, you should rest for at least 30 minutes before taking the measurement. Do not take your ear temperature when you first wake up, as the temperature of your ear on the side that is pressed will be higher than your normal body temperature. Usually the temperature is slightly different between the left and right ear, so it is recommended to take the temperature in the same ear. When taking repeated measurements, remove the probe between each measurement and take a break of at least 5 seconds before taking the next measurement to obtain the most correct result. The normal reading is about 35.5°C to 37.8°C. Users should usually take more temperature measurements to understand their own health temperature, and if there are any abnormalities, they should pay attention to body changes or ask your doctor. After each measurement, you should clean the infrared ear thermometer with alcohol to avoid blocking the ear wax to affect the measurement results and to ensure the accuracy of the next measurement.
