Ear & Forehead Thermometer

MEDICAL DEVICE CLASS 2a

The Ear & Forehead Thermometer (FDIR-V4) mainly adopts the infrared temperature measurement method to measure the human body temperature on the forehead or in the ear canal. This thermometer can be used for newborns, children and adults.

  • Key features and benefits
    • 2-in-1 device: in-ear and forehead measurement mode.
    • Reliable temperature measurement in seconds. 
    • Hygienic and safe measurement with infrared technology. 
    • Acoustic fever alarm indication. 
    • Indication of °C and °F. 
    • With low battery indicator. 
    • Automatic switch off. 
    • Incl. batteries. 
    • 2 years guarantee.
  • Content
    • 1 x ear & forehead thermometer device , incl. interchangeable magnetic measuring tip
    • 2 x 1.5 V AAA batteries
    • 1 x instructions for use
  • Instruction for use

    Ear temperature measurement:

    1. Remove the measuring tip.
    2. Put the thermometer probe gently into the ear canal and make sure you feel comfortable.
    3. When the probe enters into the ear canal, press the „measure button“ lightly. When hearing the beeper sounds, the measurement is complete and you can take out the thermometer and check the measurement result on the display.

    Forehead temperature measurement:

    1. Put on the measuring tip.
    2. Aim the thermometer probe at the center of the patient's forehead and touch the skin lightly in order to get more accurate results.
    3. Press the “measure button” lightly. When hearing the beeper sounds, the measurement is complete and you can check the measurement result on the display.

    Fever indicator:

    • If the measured temperature is between 32.0 and 37.4 °C, a long acoustic “beep” sounds.
    • If the measured temperature is between 37.5 and 38.5 °C, there will be a “beep beep”... “beep beep” sound (= the indication for “raised temperature”).
    • If the measured temperature is between 38.6 and 42.9 °C, there will be a “beep beep beep beep”...”beep beep beep”... sound.  In this case, you should consult your doctor.
  • Problems and limitations

    Certain circumstances may influence the temperature in the ear and should therefore be considered before using the Ear & Forehead Thermometer in the “ear measurement mode”, as they can influence the body temperature measurement: 

    • If you have been lying on the ear for an extended period, the ears are covered, the ears are exposed to excessive heat/cold, or after swimming or bathing. > In the event of one of these circumstances, wait 20 minutes before performing the measurement. 
    • As ear wax can affect the measurement, you should clean the ear before measuring, if necessary.

    Similarly, there are various circumstances that can influence the body temperature results given by using the “forehead measurement mode”:

    • Physical activity, increased perspiration on the forehead, taking vasoconstrictive medication and skin irritations can distort the result.
    • Holding the thermometer for too long in the hand before taking a measurement causes the device to warm up. This could lead to an incorrect measurement.
  • Further information
    • The body temperature measured in the ear may differ from other measurements taken in the mouth, rectum or armpits. Any comparison of these values is therefore futile. The temperature results measured with the Ear-/Forehead Thermometer should therefore serve as indication and in the case of high temperature should be followed up by measurements (ideally in the rectum) with a digital rod thermometer.
    • Temperature should be measured regularly to calculate the average temperature and then these measurements should be used as a basis for comparison when taking measurements in the event of a suspected high temperature.
    • Body temperature is lower in the morning and increases throughout the day towards evening.
    • Physical and, to a lesser extent, mental activities increase body temperature.
  • Storage advice

    Do not store below -25 ° C and not above 55 °C and the humidity should not be above 95%. If prolonged storage is planned, you should remove the batteries.
