8. Forehead measurement
Beurer tip
Remember:
• Physical activity, increased perspiration on the forehead, taking vasoconstrictive medication and skin irritations can
distort the measurement.
• The forehead, or the temples, must be free from perspiration and cosmetics.
• We recommend that you take three measurements on the forehead. If the three measurements are different, use the
highest value.
• If the forehead area is covered in hair, sweat or dirt, clean the area and then wait for 10 minutes to improve the preci-
sion of the measurement.
• It is important that you keep the thermometer still during measurement. Moving the thermometer during measurement
may cause imprecise measurements.
