Infrared thermometer is higher or lower than mercury thermometer how to use infrared thermometer

The infrared thermometer is an instrument that measures body temperature through infrared rays. In the same conditions of use and operation, generally speaking, the accuracy of the infrared thermometer can reach 0.1 degrees Celsius, the measurement accuracy is not worse than the mercury thermometer, so the two measurements are almost the same temperature. However, because the infrared thermometer is affected by external factors, in the measurement of forehead temperature, the measured temperature may be slightly lower, but will not affect the measurement results.

How to use an infrared thermometer:

There are two common types of infrared thermometers: forehead thermometers and ear thermometers.

When using a forehead thermometer, the instrument should be aimed at the center of the forehead, above the eyebrow position, the measurement site should not be covered by hair, and the distance from the forehead is about 5-10 centimeters between.

If the subject comes from a place where the temperature of the measurement environment varies greatly, he or she should stay in the measurement environment for more than 30 minutes before taking the measurement, otherwise the results will be affected.

The instrument should not be used outdoors or in places with strong sunlight.

Specific operating instructions may vary by instrument and brand, so we recommend that you refer to the instrument's manual to ensure that you get accurate results. If you have any questions, please contact the vendor or relevant professionals.
