How The Non-Contact Infrared Thermometer Works

With the ongoing COVID-19 coronavirus pandemic, the need for body thermometers at work, at home, and on the go has never been greater. But not all thermometers are created equal, so you need to know which one is the most effective in dealing with the prevention and spread of COVID-19.

With an infrared thermometer, you can take a person's temperature while minimizing the risk to yourself while maintaining a safe distance from potentially infected people. You can also buy a noncontact thermometer from

But how exactly does this infrared thermometer do it? We explore that question in a detailed breakdown of your average infrared thermometer and how it works.

The technology behind the non-contact thermometer: 

Infrared thermometers have several components that make it possible to monitor the thermal radiation emitted by an object or person. This setup essentially consists of a lens capable of directing infrared thermal radiation at the detector. It converts the radiated power into an electrical signal which can be read as temperature data.

After the machine compensates for the ambient temperature, the mechanism can calculate the temperature of the object it is aiming at. These are the basics of what's inside an infrared thermometer and how it works to give you a temperature reading without having to touch the object.

With all this information, you now need to better understand infrared thermometers and how they work
