In the first experiment, we acquired ...

devices are equipped with infrared (IR) sensors that quickly measure surface temperature without making any contact with a person’s skin. Their speed of measurement and the convenience of not having to sterilize them after each use before applying them to the next person makes them suitable for use in situations where mass temperature screening in many people is required. As fever is a ...

Answer: Not that I know of. I have both tools, an IR camera (and an IR “noncontact pyrometer”, which is a fancyschmancy term for an infrared thermometer), plus a Laser Measuring Tool (Leica Disto). Both work in different principles. The IR camera and pyrometer has a sensitive sensor which res...
