Is frequent use of infrared thermometers harmful to the eyes?
The principle of frontal infrared thermometer is that the heat of the human body will be emitted to the environment in the form of thermal radiation, and the human body infrared thermometer detects the thermal radiation of the human body through the built-in sensors, so as to realize the purpose of measuring the body temperature. Infrared thermography body temperature rapid screening instrument using infrared thermometry technology on the human body surface temperature non-contact rapid measurement, when the measured temperature reaches or exceeds the preset warning temperature value of the instrument for warning.
Some experts say, infrared temperature measurement ceremony LED lights issued by the time of being measured, infrared light to the head, rather than the eyes, only with infrared direct irradiation of the eyes and a very long time, may cause damage to the lens, retina, but the infrared thermometer caused by the chances of such damage is almost zero.
Can infrared rays really damage the eyes?
If the intensity of infrared rays will have a certain degree of eye irritation and damage, serious can cause cataracts, retinal damage, and even blindness. Wavelength less than 1.5 microns of infrared light, the eyes will have a certain absorption, if the infrared light directly irradiated the eyes, may make the fluid in the eye will be related to the reaction, caused by some eye diseases, infrared thermometer is not designed to emit infrared light, just to locate it, relying on the heat emitted by the human body to measure the epidemic period, please do not worry about the use of infrared thermometers.
The use of infrared thermometer:
Use of the environment
1, the use of temperature, should be between 10-40 degrees Celsius
2, can be used for multiple measurements, the highest value, 3 times can be measured temperature difference + - 0.2 degrees Celsius.
3, insufficient battery will affect the measurement effect, to replace the battery in a timely manner.
Measuring part
1, in line with environmental requirements when measuring the forehead, the thermometer from the measurement site 3-5 cm.
2, the measurement is low:
From the outdoors just into the house, forehead is very cold, will not measure or show a low temperature (about 35 degrees Celsius). It is recommended to pull up the cuffs and measure the wrist, or open the collar and measure the neck, the measurement result will be close to the real body temperature.
Precautions
1, the measurement environment below 10 degrees Celsius measurement will be inaccurate.
2, continuous use will affect the accuracy of the measurement, you can prepare a few thermometers for alternate use.
3, this method of temperature measurement is only used for the initial screening, the temperature of objections to the suggestion of using a thermometer for further measurements have been calibrated.
