Infrared Thermometers

Infrared Thermometers: The very first sign and symptom that appears in the patient’s body is fever. Disease manifestation can occur if a person is suffering from depression. To control this contagious virus, the only precaution is to distance yourself from the crowd. An infrared thermometer is used to detect human body temperature.

When you visit shopping malls for shopping, hospitals, parks, and even any government official building, your body temperature is examined by the infrared thermometer. Optimal temperature is mainly based on two factors. One is the environmental factor, and the other is the individual’s body temperature. People are much concerned about the use of the infrared thermometer in COVID-19. Here is the information about the use of infrared thermometer in COVID-19 for mass screening.

Precaution to Use Infrared Thermometer for Mass Screening

As coronavirus is contagious and can spread from one person to another. The precautionary measure is mandatory. If your job role is to check the body temperature of random people visiting hospitals or shopping malls, the best precaution is to use latex gloves. It’s better to purchase boxes of latex gloves. Change your latex gloves after every two hours and use sanitizer. Health care always comes first. The best part of using an infrared thermometer is that they are non-invasive and show results within seconds. Without wasting any time, you can measure the temperature of so many visitors at a time. An infrared thermometer is used as a mass screening tool just to detect the coronavirus. So make sure your thermal thermometer, i.e. infrared thermometer, must show an accurate reading.

Accuracy of Infrared Thermometer

In clinics and public places, the use of a non-contact infrared thermometer is most common. Just to access the body temperature of an individual, these infrared thermometers are very common. In the United States of America, mass screening for human body temperature occurred just to detect the coronavirus. However, it is notified that certain factors are involved to alter the human body temperature. That includes sweating, using air conditioning, use of make-up, and much more. The accuracy of the infrared thermometer is also disturbed by humidity.

Fever a Major Covid-19 Symptom

The leading symptom of coronavirus is fever. Most of the patients do not suffer from any other symptoms like flu and fatigue. Instead, the only sign and symptom they experience is high fever. 40% of patients are admitted for the treatment, others prefer to quarantine themselves. If you exercise daily and wear warm clothes, that can also increase your body temperature. From the journal of family medicine and primary care, it is reported that: “temperature screening is not a proven method for detection of coronavirus”

Is Infrared Thermometer Effective?

High fever can be detected by the infrared thermometer or thermal scanners. There is no such evidence available to detect the coronavirus using an infrared thermometer. High fever can be a sign of coronavirus, but further tests are required to confirm the presence of this contagious virus. Fever can also indicate that you are suffering from dengue or malaria. An infrared thermometer is effective to detect temperature, but not as effective to detect the virus. The infrared thermometer is not specific for coronavirus detection. Infrared thermometers are only effective to let you know what your body temperature is. As fever is only an early symptom that indicates its presence.

Infrared Thermometer and Sensitive Skin

Sensitive skin sometimes comes in contact with infrared radiation and becomes infected or allergic. The beam that is emitted from the infrared thermometer is bad for those people who have soft, delicate, and most important sensitive skin. The accurate temperature reading can be measured when the infrared thermometer is tested on the human wrist. This is a safer option to check the body temperature on a smaller surface area that is not sensitive to radiation.


The accuracy of the infrared thermometer for mass screening is not accurate at a point. Due to environmental factors, the change in the human body temperature occurs. For primary means to detect the coronavirus, mass screening or temperature screening is not suitable. It is very convenient to use an infrared thermometer, as deep body temperature can not be measured by this device. To measure the human body temperature more accurately for the coronavirus, one should measure the difference of temperature in the eye corner and hand. The growing concern for the use of infrared thermometers has increased much. That is what some research has done to identify its users. If you are not sure about your body temperature, you can check it twice after every two hours just to make sure if you have the early signs and symptoms of Covid-19.

Infrared forehead thermometer

An infrared thermometer is a thermometer that extracts heat from a portion of the heat radiation, sometimes called black body radiation emitted by the object being measured.

It can be used to measure the body temperature Especially the forehead. In today’s COVID pandemic, this thermometer is widely used to measure body temperature. It is used by security officials outside banks, malls, airports, and other public places.

Non-contact infrared thermometer

A person’s temperature can be measured in several ways. One way to measure a person’s surface temperature is to use non-contact infrared thermometers (NCITs). NCIT can be used to reduce the risk of cross-contamination and reduce the risk of disease transmission. Although 98.6 ° F (37.0 ° C) is generally considered a “normal” temperature, some studies show that “normal” body temperature can range from 97 ° F (36.1 ° C) to 99. ° F (37.2 ° C). It is important to understand the benefits, limitations, and correct use of these thermometers using NCIT. Incorrect use of NCIT can result in inaccurate temperature measurements.

No-touch infrared thermometer

The Braun Digital Touchless forehead thermometer is the best we’ve tested. This thermometer will guide you through the process of measuring the temperature with instructions properly printed on the front of the thermometer. Our medical professionals emphasize the importance of following instructions for the particular thermometer used because they all work a little differently.

When measuring the temperature, be sure to point the right side of your forehead with the light shining from the thermometer towards your forehead. (You can learn more about thermometer position below.) If you are too far away, a unique function of this thermometer, which is a large reading display, will tell you to move by showing “FWD”.

This ability allows us to get accurate and consistent results when we test our own forehead temperatures - our results range from 98.2 degrees Fahrenheit to 98.3 degrees Fahrenheit. While many other thermometers we tested give similarly consistent results. (Although some can vary by up to 2 degrees between each reading) but this makes us feel more confident that we are getting an accurate reading because positional light never worries that we actually read it. Forehead temperature too high or wrong place.

Braun No-Touch also works directly on the forehead, which can be easier if you use your own warmth. This is not an option available with many other non-contact thermometers. If you must use a large number of human temperatures, the non-contact option will reduce cross-contamination and reduce the risk of germs spreading.

This thermometer is easy to read, with a backlit color-coded display that shows three different colors depending on the temperature reading - green for normal reading, yellow for mild fever, and red for high fever. This quick indicator is useful if you read one at a time, for example, your kids go to kindergarten and see if someone has a fever. A brighter screen is also useful for measuring the temperature of a child in a dark bedroom while sleeping. You can also turn off the thermometer with a switch on the side so there is no beep that could alarm.

The thermometer comes with a protective cover to keep the screen and probe clean and is backed by a three-year warranty, which is significantly longer than other models we tested. When the battery life is 20%, you will also be notified by a flashing battery icon.

One problem with this thermometer is that it doesn’t have a memory function to show past readings, which we find useful with other thermometers. If you want something to keep track of your readings, this can be it. many people who have this function.

Although this thermometer is more expensive than most of the tests we tested. Instead, you get a thermometer that is easy to use, has the easiest to follow instructions and will give you the most accurate and consistent readings.
