<p>Thermometers are <a href="https://www.telpopos.com/face-recognition-tempeture-measurement-terminal" target="_blank">thermometer</a>s that maintain the highest body temperature, also known as "medical thermometers". The commonly used thermometers are glass thermometers, electronic thermometers and infrared <a href="https://www.telpopos.com/face-recognition-tempeture-measurement-terminal" rel="noopener noreferrer" target="_blank"><strong>thermometers</strong></a>.</p><p><br></p><p>1. Glass thermometer</p><p><br></p><p>Glass thermometers are common on the market. The working substance of a glass thermometer is mercury, which is measured by the expansion and contraction of a liquid by heat. Glass thermometer has the characteristics of accurate indication, high stability, and low price, no external power supply, but glass thermometer fragile, may cause mercury pollution, use is not particularly convenient, there are many people choose electronic thermometer.</p><p><br></p><p>Usage:</p><p><br></p><p>1) before use, the thermometer degree should be put below 36℃;</p><p><br></p><p>2) place the mercury in the thermometer under your armpit and measure for 5-10 minutes;</p><p><br></p><p>3) take out the thermometer and turn the scale to the scale where you can observe the mercury's arrival.</p><p><br></p><p>4) read the data, the normal temperature of the human body is 37℃, 37℃ is more than a fever.</p><p><br></p><p>Matters needing attention:</p><p><br></p><p>1) do not drink hot water or eat cold drinks before measurement, so as not to affect the actual body temperature.</p><p><br></p><p>2) the maximum temperature value of the glass thermometer is 42℃, and the temperature shall not exceed 42℃ during storage. The thermometer shall not be put into hot water for cleaning or used to measure the temperature of water and other objects;</p><p><br></p><p>3) if there is sweat under your armpits, you need to dry them and measure them again. If you accidentally release them before the time, you need to measure and time again.</p><p><br></p><p>2. Electronic thermometer</p><p><br></p><p>The electronic thermometer consists of a temperature sensor, a liquid crystal display, a button battery, a special integrated circuit and other electronic components. Can quickly and accurately measure the body temperature, compared with the traditional mercury glass thermometer, has the advantages of convenient reading, short measurement time, high measurement accuracy, memory and beeping prompt, especially the electronic thermometer does not contain mercury, harmless to the human body and the surrounding environment, especially suitable for the family, hospital and other occasions to use.</p><p>Usage:</p><p><br></p><p>1. Before using the thermometer, the head of the thermometer should be disinfected with alcohol. Press the switch and the buzzer will beep for about 2 seconds.</p><p><br></p><p>2. The monitor will display the temperature of the last side measurement, which will last for about 2 seconds. After the display may display the "℃" symbol flashing, indicating that the thermometer has been in the waiting state.</p><p><br></p><p>3. Use a thermometer to take your temperature. During the measurement, the temperature value showed a gradual rise, while the "℃" symbol kept flashing.</p><p><br></p><p>4. When the rate of temperature rise is less than 0.1℃ within 16 seconds, the "℃" symbol stops flashing and the thermometer beeps for about 5 seconds. When the thermometer has finished measuring, the body temperature displayed can be read.</p><p><br></p><p><br></p><p><br></p><p>5. the thermometer has the function of automatic shutdown, will be automatically shut down within 10 minutes after the end of the measurement.</p>
