Legal Metrology Certification For IR Thermometers

Introduction

The novel coronavirus (COVID-19) crisis has caused the sudden surge in the import numbers of the IR thermometer. Measuring body temperature has become important way to screen a large number of people at airports, malls, offices, hotels as well as in communities. These thermometers are held 3 to 20 cm away from the patient and typically measure the temperature on the forehead.

Working of Infrared Thermometers

Infrared light works like visible light–it can be focused, reflected or absorbed. It checks the human temperature by sensing the infrared energy radiated by the body. Infrared thermometers usually use a lens to focus infrared light from one object onto a detector called a thermopile. The thermopile absorbs the infrared radiation and turns it into heat. The more infrared energy, the hotter the thermopile gets. This heat is turned into electricity. The electricity is sent to a detector, which uses it to determine the temperature of whatever the thermometer is pointed at. The more electricity, the hotter the object is.
