    My Philips Avent Ear thermometer readings fluctuate

    Published on 2018-02-02

    When using the Philips Avent Smart Ear thermometer you might get different readings when you perform multiple measurements. Find out what the cause is.

    With new technologies it has become easier and more pleasant to take multiple readings. However, in most cases this is not necessary. Multiple factors will affect your reading:

    • Probe placement
    • The time of day
    • Variation in body temperature due to physical activity or illness
    • The temperature of the ear itself which can, for example, be influenced by wearing a cap or lying on a pillow
