How do Forehead Thermometers Work?
A forehead thermometer works using infrared rays for calculating the heat emitted by your body. It shows the temperature in a few seconds. But since the device comes with a temperature range for operation, you need to check it before purchasing.
What are the Types of Infrared Thermometers?
Forehead thermometers are of three types based on their functionality. These are:
1. Contact Type:
As the name indicates, the probe tip needs to be pressed on the forehead or temple for using it. Accurate results are provided by them. You can take your temperature with this.
2. Non-Contact Type:
It is a great way of checking your baby’s temperature when he is sleeping. Hold it 1-6 inches away from the forehead and scan it for knowing the reading. No contact with the skin prevents the need for disinfecting it even after using it for many persons.
3. Multifunction Type:
They provide the temperature readings through the forehead or other parts like ears. You can switch between modes as per your requirement. For use through the ears, it has to be inserted in the ear canal. This shows accurate readings but should not be used for newborn babies as it can be discomforting.
Factors to be Considered while Using a Thermometer:
1. Speed of Responding to a Temperature:
Certain models take one second to show the temperature reading whereas others may take up to 10 seconds. If you are using it for a baby, make sure that it has a low response time so that the results will be shown when the baby is not moving.
2. Storing the Readings:
Some thermometers can store up to 20 readings which is important to know the temperature fluctuations if you have a fever.
3. Unit Used:
Some thermometers use Celsius and some use Fahrenheit. It is always better to get one that can switch between the units for better convenience.

Best Forehead Infrared Thermometer in India Buying Guide & Tips:
Some points to remember while purchasing a forehead infrared thermometer are as follows:
1. Accuracy of Results:
Inaccurate temperature outputs result in the wrong diagnosis due to which the treatment can’t be done properly. So accuracy is an important factor. It is a safe practice to take a few readings consecutively and compare them so that you know if the reading is accurate.
2. Durability:
The thermometer should be durable enough to last long. Make sure that its body quality is made using good quality material.
3. Purpose for Using the Product:
Before buying the forehead thermometer, understand for whom it will be mostly used. In the case of small kids, the forehead infrared model is perfect as taking the temperature with other types of thermometers will be difficult.

Similarly, if you need a thermometer for medical use, industrial use, or measuring room temperature, different types will be used as the forehead infrared type is not suitable.
4. Backlit Feature:
Reading the temperatures will be possible if the display has a backlit feature. This helps even during the nighttime or low light conditions.

Read the temperature after removing it. It is better to add a degree to the recorded temperature for knowing the actual internal temperature of the body.
Hovering Mthod:
Switch on the device and keep it 1-2 inches away from the forehead. Keep holding the button and you can find 2 red circles appearing on the forehead. Adjust the distance of your forehead with the device until the circles merge. Make sure that the person remains still during the process.
Then release the button to hear the beep sound after which the temperature can be read. Add one degree to the result to get the core body temperature.
Drawbacks of Forehead Thermometers:
These devices can show wrong temperature readings which will hamper the diagnosis process of the patient. So it is essential to check the device’s accuracy before buying one.
