How do Infrared Thermometers Work?

In the category of thermometers, contactless infrared thermometers are paramount, especially in the current scenario. Gone are the days when a caregiver or doctor had to stick a thermometer under the tongue to measure the temperature of the human body. With technological and scientific advancements, contactless infrared thermometers are increasingly being used as they are portable, light, handy and hygienic. 

Contactless Infrared thermometers can measure temperature from a distance. The distance can be from a meter to a few miles. However, 1-meter distance is just apt. 

The first infrared thermometer to be commercially available was produced in 1931. Infrared thermometers work under a basic principle: All the things that have mass radiate energy in the form of heat. The infrared thermometer can detect the infrared (IR) rays by detecting the heat being emitted by the object against the backdrop of the surrounding. The IR rays are further funneled into a detector called a thermopile. In the thermophile, the IR gets converted into heat and then into electricity which is measured.

The thermopile becomes hotter with rising infrared energy. The amount of electricity generated by the rays reflecting from the object provides a reading that is then displayed on the thermometer. One can see the reading being displayed on the infrared thermometer within seconds.  Because of its fast deliverance of results, it is used in medical and commercial setups. 

This phenomenon is also called black body radiation. The hotter the molecules in an object get, the more they emit IR rays. In turn, the intensity of the electricity depends on how hot the object is. 

The infrared thermometers have a good reputation for accuracy and are highly reliable. They are a safe equipment to use as they ensure safe distance. One must aim the infrared thermometer at the object or person from a distance and the reading would be shown in a few seconds. This also solves the issue of plausible contamination or cross-contamination. Moreover, it is durable whether used extensively in a clinic, hospital, at home or at airports.  Apart from this, there are multiple uses of infrared thermometers.You can buy infrared thermometers in India online from us at Vertel Digital or get in touch with our sales executive.

Things to ensure to get correct temperature using Infrared Thermometer

In the wake of Coronavirus pandemic, not just the medical industry but every people-based industry is taking preventive measures to control the spread of the disease while trying to awaken the economy. As now the businesses are opening for the world.

It has become imperative to follow the World Health Organization’s suggested measures for both the visitor such as – wearing masks, using alcohol based hand-sanitizer (time to time) and using gloves, and for the visited premise- sanitization in every 2 hours, employees to wear masks, face covers, gloves, temperature to be checked using contactless infrared thermometer before entering the premise, sanitization of packaging before leaving the premise and other precautionary measures.

Today, checking the temperature of every person has become imperative to examine if they have any fever-related symptom of Coronavirus disease while trying to not come in contact with the person. Contactless thermometers are being used at various check-points, and in this blog, we are going to talk about things to keep in mind to ensure that correct temperature is captured in the contactless infrared thermometer:

1. Measuring temperature outside the required area: Sometimes it gets difficult to measure the temperature of the human body as there are other factors in place that affect taking the correct temperature. In such a scenario, the person taking the temperature must follow the ‘distance-to-spot’ ration as mentioned on the product they are using. This will enable you to take the correct temperature unaffected from any external factor.

2. Centre of the forehead: The user must try to angle at the centre of the body’s forehead from a distance to measure the temperature correctly. This practice must be diligently followed for each examination to ensure that there are no discrepancies later.

3. Avoid any obstructions while measuring: External factors like steam, mist, dust in between the target and the handheld infrared thermometer at times, which must be avoided at all times as it may affect the temperature readings.

4. Avoid temperature shocks: It is suggested that the contactless infrared thermometer is switched on at least 20-25 minutes before it has to be used to bring the device to normal room temperature. This is suggested for all kinds of environments, especially warmer and colder surroundings. If the device is not given enough time to come to its normal temperature, it may be in a temperature shock which can be a reason for faulty measurements.

Further, we at Vertel Digital suggest that the user must keep the lens of the thermometer clean and free of scratches. All the above stated measures are important to get accurate readings. In the previous blog we talked about the common uses for infrared thermometer, you can check that out too.

4 Common Uses of Infrared Thermometer

Infrared thermometers are required for one or the other practical reasons at home and many other places. These devices are handheld, operate from a distance and display temperature after scanning the object or area it is targeted at. Further, it is used to read a particular spot of a surface, human body, wall, automobile etc.

In recent times, due to the unprecedented spread of novel Coronavirus, contactless infrared thermometers have come in the lime light. Well, finding thermometer can be a difficult task, but here at Vertel Digital, we bring to you the best buy infrared thermometers in India.

There are various uses for an infrared thermometer, and in this blog, we are going to discuss the 4 most common uses of it to help its users benefit from the same:

1. Cooking/Professional Kitchen: Though it is very unconventional to use the infrared thermometer for cooking, but it has come as one of the most handy and innovative invention as a lot of chefs across the world can use an infrared meter to detect the temperature at which their food/meat is being cooked. This device is even more important as fine restaurants like to serve their food at a certain temperature- hot or cold, and thus can be used during cooking or at a kitchen.

2. Hospitals/Clinic: There are over 4.9 million people worldwide who have contracted COVID-19, and the number is still on the rise. To protect the doctor, medical personnel and other warriors who are helping protect the community, an infrared thermometer can be used as these essential workers can use the instrument from distance to check or measure temperature of human body from at least 1 meter away.

3. Checkpoints: Essential workers like police, security guards at hospitals, grocery stores, etc. are the safeguard between a safe, septic and clean world and the one where Coronavirus prevails. To keep the people and the area beyond check point Corona-free, people check for temperature and allow people who have temperature within the normal range of 97-98.6 degree Fahrenheit.

4. Home: At home, there can be so many different uses of an infrared thermometer like from checking the temperature of the milk before feeding to the child, or the toys that children want to play with after they have been in the sun the whole day, or the properly cooked meat that you are preparing in your lawn over a barbeque or even in winters when you heat the water before taking bath.

There are plenty of places where an infrared thermometer can be used or benefitted from. People working at a factory can also use a thermometer to detect the temperature of the boiler room before entering. Vertel Digital brings to you the best quality infrared thermometer that can be used at your convenience and wherever you like.
