Is frequent use of infrared thermometer harmful to eyes?
The principle of an infrared thermometer is that the body's heat is emitted into the environment through thermal radiation. The infrared thermometer detects the body's thermal radiation through a built-in sensor, thereby achieving the purpose of measuring body temperature. The infrared thermal imaging temperature rapid screening device uses infrared temperature measurement technology to measure the surface temperature of the human body in a non-contact and rapid manner. It is an instrument that alerts when the measured temperature reaches or exceeds the preset warning temperature value.
Experts have stated that the infrared temperature measurement ceremony LED light emits infrared radiation that illuminates the head, not the eyes, during measurement. Only by directly irradiating the eyes with infrared radiation for a long time can it cause damage to the crystalline lens and retina. However, the probability of such damage caused by an infrared thermometer is almost zero.
Can infrared radiation really damage the eyes?
If the intensity of infrared radiation is high, it can cause certain irritation and damage to the eyes, and in severe cases, it can lead to cataracts, retinal damage, and even blindness. Infrared radiation with a wavelength less than 1.5 microns will be absorbed by the eyes to a certain extent. If the infrared radiation directly shines on the eyes, it may cause related reactions in the liquid in the eyeball, leading to some eye diseases. Infrared thermometers are not used to emit infrared radiation, but only for positioning. They rely on the heat emitted by the human body to measure. Please feel free to use infrared thermometers during the epidemic.
Instructions for using an infrared thermometer:
Usage environment
1. The operating temperature should be between 10-40 degrees Celsius
2. Multiple measurements can be taken, with the highest value being 3 times, measuring a temperature difference of+-0.2 degrees Celsius.
3. Insufficient battery will affect the measurement effect, so it is necessary to replace the battery in a timely manner.
Measurement location
1. Measure the forehead when meeting environmental requirements, and keep the thermometer 3-5 centimeters away from the measurement site.
2. Low measurement:
As soon as I enter the house from the outside, my forehead feels very cold and I may not be able to detect or display a low temperature (around 35 degrees Celsius). Suggest rolling up the cuffs and measuring the wrist, or opening the collar and measuring the neck. The measurement result will be close to the true body temperature.
matters needing attention
1. Measurement environment below 10 degrees Celsius will result in inaccurate measurements.
2. Continuous use can affect measurement accuracy, so several thermometers can be prepared for alternating use.
3. This temperature measurement method is only used for initial screening. For those who have objections to body temperature, it is recommended to use a thermometer for further measurement and calibration.
