What is the science behind the infrared thermometer?
In nature, any movements higher than the absolute zero (-273 ° C) exist in motion of molecular and atomic irregularities. In this process, the objects are constantly releasing radiation energy outward. The size of the radiation energy is closely related to the temperature on the surface of the object. For example: the normal temperature of the human body is between 36 and 37 ° C, and the radiation energy is infrared with a wavelength of 9 ~ 13 μm. The temperature measurement principle of infrared thermometer is to detect the infrared wavelengths of the specific parts of the human body and transform into temperature reading through electronic circuits.
Different infrared thermometers, the biggest difference is not the principle of temperature measurement, but to find the process of specific parts. There are automatic identification, mostly used in places with large people; there are those who can "manually aim" from a long distance, and most of them can emit a red light spots to aim at the temperature measurement point; there are also those who need to measure the measured head to the measurement position. So how to use the instruction manual to be used correctly.
Usage of the infrared thermometers
- Before using for the first time, be sure to read the product manual to understand the usage, precautions and maintenance.
- Check whether the battery of the thermometer is sufficient. For rechargeable thermometers, make sure it is fully charged.
- Place the thermometer in the measurement environment for at least 15 to 20 minutes to adapt it to the temperature of the current environment.
- Use a medical alcohol cotton ball to gently wipe the detection head to ensure that there is no stain, and then wait for the alcohol to completely evaporate before measuring.
- When measuring, just hold the handle of the infrared thermometer, then 3-5 cm away from the part to be measured (such as forehead, armpit), and then press the button with your finger.
