Thermometer Guns

The power of infrared thermal imaging has been covered before, particularly as thermal imaging via thermographic cameras, e.g., from Opgal, Flir or others. The coronavirus has brought such thermal imaging technologies to a new level of awareness thanks to the now iconic images of masked officials in China aiming a thermometer “gun” at a traveler’s forehead. These handy if not completely accurate devices have been deployed by both government officials and private citizen to screen people for fevers associated with the COVID-19.

A thermometer gun is a device that contains an infrared sensor that quickly measures surface temperatures without making any contact with the surface, e.g., a person’s skin. Such devices have gained popularity in recent years to slow the spread of diseases like SARS and Ebola.

The popularity of thermometer guns combined with people’s fear for the COVID-19 has caused a shortage of these useful device. In response, distributors like Amazon and other have been working to shore up supplies while at the same time working to stop the artificially-inflated prices of thermometer guns that typically cost under $100 US.

Of course, you could always build your own (see next slide).
