Thermometer Laser Point
How do those “light” or “laser” thermometers work?
It’s difficult for me to ask this question correctly, because I’m not exactly sure what it is.
I saw a guy at the grocery store the other day pointing a laser or red light thing at some of the product.
I asked him what he was doing, and he said “I have a refrigeration alarm going off, but don’t know which case is running warm.” And he went on to say that that thing he was holding would take the temperature.
I asked how it worked, and all I got in reply was, “I have no idea.”
The light is only for aiming, it does not do the measuring.
The device focuses infra-red emissions from the target area (marked by the laser) onto an IR sensor, the same way as IR cameras can show where the heat loss is on a building.
