Forehead Thermometer Advantages

Infrared Forehead Thermometer measures core body temperature, which is the temperature of a body’s vital organs. (See Figure 1) This thermometer is designed to measure the temperature of the skin surface over the temporal artery, a major artery of the head. The temporal artery is connected to the heart via the carotid artery, directly leading from the aorta, the main trunk of the arterial system. It offers constant blood flow. Therefore, body temperature changes are reflected sooner in the forehead than they are in other parts of the body such as the oral, rectal, and underarm.

Temperature Taking Hints

To ensure that the reading always reflects the body temperature accurately, you need to take account of the following factors which may affect an accurate reading.

It is important to know each individual’s normal temperature when they are well. This is the only way to accurately diagnose a fever. To determine normal temperature, take multiple readings when healthy. Re-measure with a standard digital thermometer for confirmation.
Users must be inside for 30 minutes before taking a measurement.
Note: Users and the thermometer should be in the same ambient temperature for at least 10 minutes before taking a reading.
Users should not drink, eat, or be physically active such as bathing, showering, shampooing, and hair drying before/while taking the measurement. Remove hat and hair and wait 10 minutes before taking a reading.
Oils or cosmetics on the forehead may give a lower temperature reading than the actual one. Remove dirt from the forehead before taking a measurement. Wait at least 10 minutes after washing the forehead area before taking a reading.
Holding a hand on the forehead for any length of time will affect the temperature reading.
Do not take temperature over scar tissue, open sores, or abrasions.
Do not use the thermometer on a perspiring or sweating forehead, as this may affect the reading.
Don’t take a measurement while or immediately after nursing a baby.
Do not take temperatures with this thermometer near places that are very hot, such as fireplaces and stoves.
The probe window of the thermometer is the most delicate part of the device. Do not touch the probe window. The accuracy of the reading may be affected if the probe window is damaged or dirty.
If the thermometer is stored in a significantly different environment than the testing location, place it in the testing location for approximately 30 minutes prior to use.
It is not intended for use in the oxygen-rich environment and presence of flammable anesthetic mixture with air, oxygen, or nitrous oxide.
