How Do Infrared Thermometers Work?


The most basic way to describe an infrared thermometer is a contactless way to check temperature amongst humans. With COVID-19 on an outbreak, the most hygienic way to check the temperature is to use an Infrared thermometer. So, the chances of transmitting the disease and infection reduce.


One of the major symptoms of being affected by coronavirus is having fever, amongst other symptoms like dry cough, sore throat, etc. Hence, given the current situation, the most popular choice of checking the temperature both at homes and hospitals is the use of an infrared temperature. 


Now moving on to how does an infrared thermometer work? The thermometer scans the infrared heat emitted by a human body from a distance. It immediately reflects the reading of temperatures on the LED Display within a few seconds only. If the reading is green in colour, then the scanned person does not have a temperature, but, if the reading screen turns red then the scanned person has a fever. 


Segun infrared thermometers are fantastic silent temperature checking devices, even if your child is sleeping you can conveniently measure the body temperature without disturbing the child.


Moreover, you can switch modes between human temperature checking and object temperature checking. The modes can be chosen on the mode switch key, making our thermometers multi-functional. 


For convenient reading, you can switch between Celcius and Fahrenheit, by using the switch key.
The Segun thermometer can also save up to 99 readings of temperature recordings. 

The following steps sum up how to use an Infrared thermometer: 

  1. Set the Reading to Fahrenheit or Celsius.
  2. Set the Mode to Body/ Food/ Object Check.
  3. Turn on the Laser Gun
  4. Aim the Gun
  5. Get Close
  6. Pull the Trigger
Pulling the trigger gives an instant infrared reading on the gun’s display.
