The AIQURA infrared thermometer quickly and accurately measures temperature (in seconds) for both adults and children. It can also measure surface temperatures, such as bathwater or baby bottles. Features: • Built-in infrared laser pointer for precise, non-contact measurement • Fast 1-second measurement • Memory for the last 16 measurements • Measuring distance: 3-5 cm • Accuracy: ~0.2 ℃ • Large, clear backlit display • Automatic shut-off after 15 seconds • Mute mode for silent temperature measurement • Selectable Celsius or Fahrenheit • User manual (English) The thermometer operates in room temperatures from 16-35℃ and requires 2x AAA batteries (not included). Read instructions before use. Open the battery compartment and insert 2 AAA batteries. Press "SET" to select body or surface temperature measurement. Hold the thermometer's sensor 3-5 cm from the target. Press and hold the button to start; the reading will appear on the display. Repeat measurements for accuracy. An infrared thermometer measures external skin temperature. While fast and contactless, it's not comparable to rectal measurement. External factors can affect readings; therefore, it's primarily for assessing whether a fever is present. The difference between rectal and forehead temperature can be up to 1.5°C. If a fever is indicated, confirm with a rectal thermometer (for children) or rectal/oral thermometer (for adults). NOTE: Sealed hygienic item – returns are only accepted if the packaging is unopened.
