Operation Guide for Human Thermometers for Flu Screening
Operating Instructions for Human Infrared Thermometers for Influenza Screening
For influenza or epidemic fever screening, handheld human infrared thermometers, which can measure temperature quickly and accurately within seconds, are indispensable temperature measuring tools in daily life.
Its working principle is to measure the surface temperature of the human forehead, and then calculate the actual body temperature according to the correlation between forehead temperature and body temperature. The optical assembly of the detector collects the energy emitted and reflected by the forehead onto the sensor. Electronic components convert this signal into a temperature reading displayed on the panel. When the reading exceeds the high-temperature alarm threshold, the instrument emits an audible alarm and the red warning light turns on. It is an extremely important device in modern medicine.
Human thermometers are mainly used for body temperature screening in public places such as entry-exit ports, airports, stations, wharves, hospitals, government offices, factories, schools, hotels and office buildings. They help screen people with fever symptoms to reduce transmission and the spread of epidemics.
There are many types of thermometers available on the market. The two most common types are industrial infrared thermometers and dedicated human-body thermometers. It should be noted that industrial infrared thermometers are only used to measure the surface temperature of industrial objects and cannot be used for human body temperature measurement. Large measurement errors will occur if industrial thermometers are used on human bodies. Therefore, professional human thermometers must be used for influenza screening.
Infrared ear thermometers measure ear temperature and complete the measurement within one second. Since the eardrum and ear canal are less affected by ambient conditions, infrared ear thermometers can measure body temperature accurately. Human ear temperature is generally 0.4 °C higher than axillary temperature. The readings of infrared ear thermometers convert the fever threshold for axillary temperature into the corresponding threshold for ear temperature.
