What Does the Infrared Thermometer Measure

Infrared (IR) thermometers enable you to measure temperature quickly, at a distance, and without touching the object you’re measuring.

What is considered a fever with an infrared thermometer?

Read the thermometer screen. Temperature is less than 35°C, take temperature again. Temperature is 38°C or higher, this person has a fever.

How does an infrared thermometer measure temperature?

Infrared thermometers employ a lens to focus the infrared light emitting from the object onto a detector known as a thermopile. The thermopile is nothing but thermocouples connected in series or parallel. When the infrared radiation falls on the thermopile surface, it gets absorbed and converts into heat.
