Common questions concerning forehead temperature

  1. What is the forehead temperature?
    Forehead temperature is the same temperature as the arterial blood supply under the skin. It is the best determinate of body temperature, and unaffected by the artificial errors and time delays of oral and rectal methods.
  2. How to take forehead temperature properly?
    Gently touch the probe to center of forehead or no contact about 5-10 cm distance the probe to center of forehead. Make sure remove anything covering the area to be measured (hair, hat, wig, and bandages). Failure to do so may insulate the area, resulting in false readings. Press the “SCAN” button on the thermometer for the reading.
  3. Why is a forehead temperature is more accurate than ear temperature?
    Ear thermometers are considered inaccurate because the positioning of the probe in the ear canal might affect the accuracy. The forehead thermometer scans the forehead area for temperature given off by the arterial blood supply under the skin without worrying about correct positioning. The gentle scan is comfortable and not invasive.

Temperature measurements are impacted by the type of measurement method used.

Measurement method Normal temperature range Fever temperature range






NOTED: Measurements for some adults may be lower

than 35.0℃(95.0℉)

A temperature that is 0.6~0.8℃ (1.0~1.5℉)higher than usual. It is highly recommended that you use our IR Forehead Thermometer to

establish the normal temperature range for each person.
