If this year, the person who cares about your health most must be the uncle security guard downstairs in the community and company. After all, when they see you, they will definitely pick up a forehead thermometer to help you take your temperature. In special times, temperature measurement is not only the first line of defense for our epidemic prevention work, but many people have also developed a good habit of taking body temperature at home. But in many cases, due to the influence of external factors, the forehead thermometer cannot measure the accurate body temperature at one time, and some even take seven or eight times to get the accurate value. The daily temperature measurement is either too high or too low, which makes many people's hearts full of doubts.
Since everyone is concerned, let's just say something seriously: How does the forehead thermometer work? How to use the forehead thermometer correctly?
1. How does the forehead thermometer work?
The infrared forehead thermometer measures the forehead of the human body. It collects the infrared radiation emitted by the body surface, receives it through the sensor, and then transforms the algorithm to help us understand the trend of body temperature and quickly display our body temperature.
Take KIEYYUEL infrared forehead thermometer as an example. It has a built-in Gaoling sensor and 50 sets of memory chips. Through non-contact infrared measurement, it accurately recognizes the infrared rays emitted from the human forehead surface. After algorithm conversion, it shows our Body temperature at that time. Therefore, there have been rumors that "the infrared rays of the forehead thermometer will cause permanent damage to the eyes", which is not accurate. The forehead thermometer only collects infrared rays and does not emit infrared rays.
You may also question "What are the built-in sensors of the forehead thermometer for?" In fact, their role is to help the forehead thermometer to sense changes in the measurement environment, reduce the impact of changes in the environmental temperature on the measurement, and also affect the body temperature. The accuracy of the acquisition is corrected to ensure that accurate measurement can be achieved when the environmental temperature difference is large when the operating environment is outside the machine.
2. How to use the forehead thermometer?
As a forehead thermometer, the initial design inspiration was to measure the forehead, and clinical experiments are also collected in the human forehead measurement, and because the wrist is at the end of the human body, its ability to reflect the true temperature of the human body is poor. Therefore, the standard practice is to use a forehead thermometer to measure the forehead.
Take KIEYYUEL infrared forehead instrument as an example: when measuring, point the machine at the middle of the forehead, avoid clothing or hair blocking, and measure within 3 cm from the forehead.
