How Does A Digital Infrared Thermometer Work & Why Is It Better?

Holding a fragile glass tube filled with poisonous metal under the tongue for a minute just to measure the body temperature sounds absurd now. Well, thankfully, those days are gone. This is the era of contactless and effortless detection of body temperature. And digital infrared thermometers are the new heroes of the temperature scale world for being the most hygienic and convenient device for checking the body temperature of adults and kids. 

IR thermometers are the best option for detecting the body temperature of infants and children. Also, these Non-Contact Infrared Thermometers emerged as a great help during the latest COVID-19 pandemic. It allowed mass testing without any threat to health and hygiene. Moreover, these thermometers have a strong and rapid accuracy level, which was really needed during the pandemic. 

Thus, it’s time to get rid of the old, fragile, and poisonous mercury thermometers. And enjoy the latest technology and features of IR thermometers for easy and safe use. 

Types Of Thermometers

Well, if you are considering why we are supporting infrared thermometers above others, you must look at the different types of thermometers available in the market. 

Digital Stick Thermometer

Digital thermometers show the reading digitally on the screen attached to the thermometer’s body. These are used under the tongue or armpit. However, it is important to wipe the thermometer with alcohol wipes to disinfect it.

Tympanic (Ear) Thermometer

Ear thermometers or Tympanic thermometers measure the temperature inside the eardrums using IR. These thermometers can measure the temperature within seconds. They are most useful in measuring the temperature of babies or of people who find it difficult to sit still. 

Infrared Thermometer

Infrared thermometers read temperature without body contact. These no-contact thermometers are the easiest to use. Just point at the forehead or wrist, press the trigger, and the results will flash. Well, how simple is that? 

Strip-Type Thermometer

The strip-type thermometers are best for checking the body temperature of infants. The plastic strip is placed on the forehead, and it shows the result. However, these are a bit tricky, and the results can be inaccurate sometimes. 

Mercury Thermometer

As the name suggests, mercury thermometers have mercury inside the glass tube. The mercury expands and contracts in response to the temperature, and that can be read on the scale. However, these thermometers are highly poisonous. Breaking the glass tube releases the mercury inside, which can lead to mercury poisoning.

Why Should You Choose An Infrared Thermometer?

Infrared thermometers are the best choice when buying a thermometer. They are available in vast variety and check the temperature within a frame of seconds. At the same time, other thermometers take time to perform the calculations and give results. Thus, the quick response time and ease to use make IR thermometers the best buy. 

Benefits Of Using An Infrared Thermometer

Infrared thermometers gained popularity, especially during the pandemic, for their non-contact feature. These are also known as NCIT. Here are some of their benefits

  • Easy to use
  • The no-contact feature reduces the risk of contagious diseases.
  • Rapid reading of temperature.
  • Easy cleaning and handling. 
  • Can measure temperatures of a wide range. 
  • Convenient for mass use
  • Durable

Overall, the points mentioned above justify the surge in the usage of IR thermometers. These are efficient and convenient for any use. 

How Does A Digital Infrared Thermometer Work

Infrared is radiation in the electromagnetic spectrum along with visible light, UV light, etc. Every object to ever exists has mass and energy. This energy gets emitted in the form of heat. An increase in the movement of atoms creates the release of more heat. 

Infrared thermometers capture the infrared radiation coming from that object. This type of thermometer has a lens that focuses on the IR then it gets transmitted to the internal circuit of the thermometer for detection. After that, the detector converts the thermal energy into electrical energy. 

There are two types of detectors:

  • Thermal detectors
  • Optical detectors

The electrical energy converted by the detector is then passed from the analog to the digital converter. At last, the microprocessor digitally gives the final reading in the display. 

This whole process looks like a lot, but the results are rapid. 

How To Use A Digital Infrared Thermometer

Here are the steps to use a digital infrared thermometer to get accurate results.

Step 1: 

Press the power button on.

Step 2:

Wait for a minimum of 15 minutes to let the device warm up.

Step 3:

Put the thermometer on the body reading settings.

Step 4:

Step 5:

Ask the person to take off their glasses or hat if they are wearing any.

Step 6:

Hold the thermometer at a gap of 5-6cm from the forehead or wrist.

Step 7:

Press the trigger to measure the temperature

Step 8:

Read the screen. After that, take action according to what is displayed.
