Laica ear thermometer  with an elegant, lightweight and user-friendly design. With advanced infrared thermal induction technology, the body temperature can be measured accurately, absolutely smoothly, suitable for both children and babies.

The instrument is equipped with an LCD screen, a time setting function and an audible alarm system at the end of the measurement.

The thermometer stores 10 measurement results in memory so you can look up them easily

Laica ear thermometer with multi-function: It is used not only to measure ears but also to measure ambient temperature and measure surface temperature of liquids.



To ensure accurate measurement results, make sure the infrared head guard is clean and dry before measuring, and clean the location where the probe will be exposed. Make sure the probe and ears are dry.

Improper hygiene can cause the probe to deviate from actual results.

  • Clean the ear cavity where the transducer will make contact.
  • Put a protective cap on the infrared probe of the device. (press down until the red marker holds on to the protective cover). To keep clean, protective covers should be replaced before each use.
  • For accurate results, gently pull the ear outward to straighten the ear canal. And so that the transducer could make contact with the eardrum 
  • Start the thermometer by pressing the button. The device is ready to measure when producing two short sounds.

Then press the TEST button to start the measurement. When the measurement is completed, the device will emit a short beep, the measurement results will appear on the screen. (This process will take about 2 to 5 seconds depending on the body temperature of the person measuring).

  • Remove the probe from the ear. Measurement results are displayed on the screen. When the measurement result is below 37.8 ° C, the screen will display a symbol (smiley face). When it exceeds 37.8 0 C, the symbol (thin face) will appear.

The temperature measured in the ear is equivalent to the oral measurement temperature.

  • The thermometer will automatically disconnect after 1 minute if not in use or can be quickly turned off by pressing the “power” button
  • Wait about 5 seconds (after the device emits 2 short sounds) to measure the next time.

  • Press the “TEST” button to measure the temperature of the liquid surface (water bottle, milk bottle …) by putting the probe 1cm to 3cm from the surface to be measured
  • To return to the body temperature mode, when the device is in the state, press “O / I” and “TEST” at the same time until the thermometer beeps twice and the icon displays (the ear).
  • When the thermometer is turned on, the display shows the measurement results at the last function used.



The device should be replaced when the battery display “battery shape”, or when not on the power. Before replacing the battery, make sure the device is powered off.

To review the measured results, when the thermometer is on, press and hold the “O / I” button for about 3 seconds, the MEM symbol will display in the upper right corner of the screen along with the number number 1 – is the nearest measurement result, to switch to other measurement results, please continue to press the button: “source”

The display screen:

  • The number of the result of the measurement in memory (1 = most recent result, 10 = farthest result).
  • “MEM” is displayed in the upper right corner of the screen.
  • Symbols for measuring body temperature or surfaces (SCAN function).
  • Time of measurement (day, month, year, hour of measurement).

The stored value is displayed for about 1 minute. 1 minute later if not in use, the device will be turned off

  • The probe should be cleaned with alcohol-soaked cotton before and after each use and always kept the infrared tip completely dry. Care should be taken as this is the most sensitive part of the device.
