Description
Human body temperature is divided into internal body temperature and body surface temperature. Generally speaking, body temperature refers to the body temperature, and the temperature closer to the body temperature is the temperature of the mouth, rectum or armpit. Body surface temperature refers to the temperature of the skin on the surface of the human body, such as the temperature of the forehead and wrist surface.
Thermometers used for body temperature measurement can be divided into two categories: contact thermometers and non-contact thermometers. Contact thermometers include commonly used glass thermometers and medical electronic thermometers, which are generally placed under the armpit, mouth or rectum. After 5-10 minutes of heat conduction time, the body temperature can be measured. The accuracy of this thermometer is relatively high, generally 0.1℃-0.2℃.
Non-contact thermometers include infrared forehead thermometers, infrared screening instruments, infrared ear thermometers, etc. Infrared forehead thermometers are commonly used thermometers in the hands of inspectors. Infrared screening equipment is a relatively large thermometer with infrared cameras and large screens seen in large public places such as stations and airports. There is also a less commonly used infrared ear thermometer. The measurement principles of these three non-contact thermometers are the same, that is, the principle of infrared rays is used to measure the body surface temperature of the human body and convert it into the internal temperature to determine whether the human body has a fever. The accuracy of this kind of thermometer is lower, generally 0.3℃-0.4℃.
Non-contact technology for safe and hygienic use: built-in infrared temperature sensor, brav infrared forehead thermometer thermometer can measure body temperature within 1.2 inches from the center of the forehead, without physical contact with people
High precision through three-point sensing: Ultra-sensitive infrared sensors collect over 100 data points per second, while distance and environmental sensors work together to record other variables to ensure accurate temperature measurements every time.
Simple, Fast, Clear and Quiet: Designed with an intuitive one-button control, the thermometer takes just a second to read and display the temperature, even in complete darkness. When reading the temperature, the device sends a gentle vibration notification to the handshake.
Measuring with a glass thermometer is the most accurate, but it is slow and inconvenient to use. Infrared forehead thermometers are convenient and fast to measure, but have low accuracy. Generally speaking, more than 37.3 ℃ is a fever, which refers to the body temperature of the armpit. The infrared forehead thermometer must be converted into the temperature of the armpit to judge. Combining the advantages of the two thermometers, it is generally recommended to use an infrared forehead thermometer for preliminary screening and a glass thermometer for accurate judgment. Just like checking for drunk driving, using an alcohol breather for initial screening, blood must be drawn to accurately determine.
