Question 1: What kind of environment does the thermometer need to measure?

A: The working environment of the infrared frontal thermometer is generally between 16-35 ° C. If you work in the outdoor low temperature environment for a long time, the obtained value is prone to deviation. It is recommended to use in indoor environment without wind. In addition, some infrared frontal thermometers have both matter temperature mode and body temperature mode, so ensure that the infrared frontal thermometer is placed in body temperature mode.

Question 2: How to use to get accurate body temperature?

A: The infrared forehead thermometer measures the midpoint of the measured object from the brow to the hairline (also known as the forehead center). The measurement distance should comply with the requirements of the manual, the general distance is about 1-5 cm, to ensure that there is no hair, sweat, hat, etc. To repeat the measurement, first remove the infrared thermometer probe head, and then perform the next measurement after an interval of 5 seconds.

Question 3: Why does the measured body temperature sometimes fluctuate between high and low?

A: The environment the subject is in can affect the reading. For example, the warm air in the car for a long time, the outdoor low temperature environment for a long time, and the intense exercise may cause the forehead surface temperature to be temporarily high or low.

Question 4: What should I do when my body temperature rises and falls?

A: It is recommended that the subject should wait for the body temperature balance before measuring. For example, turn off the heating in the car when the temperature measurement point is approaching, or get off the car at the temperature measurement point. After strenuous exercise, rest and adjust for a few minutes before measuring.

Question 5: Forehead temperature measurement is always inaccurate, is there any other way?

A: The use of handheld infrared thermometer, in principle should be strictly in accordance with the instructions to operate to ensure the accuracy of the quantity; It is normal to take measurements in different parts of the body and have slight deviations in the results. In winter and spring, due to the low temperature, when measuring people entering the room from the outside or using the thermometer outside, it is recommended to measure the part covered by clothes or scarves, such as the wrist or neck, so that the value can be more realistic.

Question 6: Many places do not have the temperature measurement conditions in the room, how to measure in the low temperature outside?

A: There are two ways. Method 1: First measure a reference temperature for people without fever (such as yourself or colleagues), and use it as a benchmark, once it is significantly higher than the benchmark temperature, immediately take a second measurement. Method 2: Attach the warm baby with a low temperature to the outside of the thermometer to help maintain the normal working temperature.

Question 7: The current temperature gun is difficult to buy, industrial infrared thermometer can be used to measure the temperature of the human body?

A: Usually the measurement range of industrial infrared thermometers is 30℃-1000℃, and the measurement accuracy is generally greater than ±1.0℃ in the human body temperature range, which is not suitable for human body temperature measurement.

Question 8: How long does the frontal thermometer need to be calibrated?

A: The use of each thermometer environment, the use of different, such as the current non-compulsory verification of measuring instruments, there is no uniform provisions, users can decide according to the frequency of use and use. If the frequency of use is higher, the calibration cycle can be shortened accordingly.

Question 9: Does the newly purchased frontal thermometer need to be calibrated?

A: In general, although the new frontal thermometer after the factory inspection, but considering that some enterprises are batch by batch inspection, as well as product transportation factors, it is recommended to calibrate before use to ensure that the frontal thermometer quantity value is accurate and reliable.

Question10: If there is a real need, how to submit the inspection?

A: At present, metrology departments all over the country are fully engaged in the front line of epidemic prevention and control to ensure that the infrared thermometer value is accurate and reliable. Local metrology departments have opened a green channel for the service of temperature measurement equipment for epidemic prevention and control, and you can contact local metrology institutes if you have testing needs. Shanghai Institute of Measurement and Testing Technology is conducting free testing of frontal thermometers, ear thermometers and medical electronic thermometers used in public places, but because of the current testing demand, it is recommended that communities, shopping malls, office buildings, parks and other collective inspection.
