  • How do infrared thermometers work?

    Infrared thermometers capture the invisible infrared energy naturally emitted from all objects warmer than absolute zero.

  • Why the thermometer is unable to power on?

    1. The reason might be no battery inserted, please Insert qualified battery 2. The reason might be battery in wrong polarity, please take out battery and reinsert correctly 3. The reason might be low battery level, please change new battery

  • The thermometer stuck at the boot interface or the screen flashes

    1. The reason might be the thermometer is in abnormal reset, please take out the battery and wait for 1 minute and insert the battery again 2. The reason might be low battery level, please change new battery

  • The thermometer human test display is Hi

    1. The reason might be the result is higher than 43.0℃, please take out the battery and wait for 1 minute and insert the battery again 2. The reason might be the person to be tested has just returned from the hotter environment to the measuring environment, please keep the person to be test in the measuring room at least 20 minutes before measuring according to the user manual 3. The thermometer is taken from an environment with large temperature difference and the time for the thermometer to stay in the measuring room is not long enough, please keep the thermometer in the measuring room at least 20 minutes before using according to the user manual.

  • Why the thermometer human test display is Lo?

    1. Use Object mode to measure human temperature, please switch to human body mode and measure again 2. The infrared sensor is dirty, please clean the infrared sensor and keep it in the measuring room for at least 20 minutes before using according to the user manual 3. The person to be test has just returned from the hotter environment to the measuring environment, please keep the person to be test in the measuring room at least 20 minutes before measuring according to the user manual 4. The thermometer is taken from an environment with large temperature difference and the time for the thermometer to stay in the measuring room is not long enough, please keep the thermometer in the measuring room at least 20 minutes before using according to the user manual. 5. The body surface temperature is actually low in low temperature environment. It’s a normal phenomenon. Please keep the patient stay in a 25℃ room for 20 minutes and measure again.

  • Why the thermometer test display is Lo in forehead mode?

    1. The person to be test is blown by the fan or air conditioner, please move to another position other than the vent before measuring 2. Measuring distance is too far or not aiming at the right position of forehead, please ensure the infrared sensor is aim at the forehead correctly and the measuring distance is within 5cm. 3. Patient’s forehead is covered by hat or hair etc. Please remove the cover before measuring

  • Why use non-contact infrared thermometers?

    Non-contact infrared thermometers use infrared technology to quickly and conveniently measure the surface temperature of objects. They provide fast temperature readings without physically touching the object. You simply aim, pull the trigger and read the temperature.

  • The measurement results are different from other types of thermometers

    The body temperature of different parts is varies greatly and cannot be compared horizontally. For example, the temperature difference of ear canal, armpit, mouth, skin, rectum and other normal conditions may exceed 2 ℃. It is recommended to longitudinally compare the results of using the same thermometer at the same location at different times

  • What is the ideal way to measure body temperature?

    Measuring the “core” body temperature would be ideal. The core temperature is the temperature of the vital organs such as the heart and brain. Since these sites are not directly accessible, other sites for temperature measurement have been identified. 

  • Why the measurement results are different from the same kind of thermometers of different brands?

    The display temperature reference position of the same kind of thermometers of different brands may be different. For example, the forehead thermometer of brand A may refer to ear temperature while the forehead thermometer of brand B may refer to axillary temperature ,it is not recommended to compare. It is recommended to longitudinally compare the results of using the same thermometer at the same location at different times.
