IR thermo scan guns that are "not for human use"

[intrepidity]

I've got one and finally decided to Google the answer to why it should not be used on humans (aside from the obvious dont-aim-laser-at-eyes).

Turns out, it totally can be used to take one's temperature,, but there are a few things to understand first. Hopefully some of you also may find this useful.

With proper technique, general-purpose infrared thermometers might be used as a substitute scanning tool for detecting elevated body temperatures. We offer the following information and cautions:

Forehead temperature is several degrees lower than core body temperature of 98.6 F (37 C). Clinical forehead thermometers make a mathematical adjustment to display an equivalent oral temperature.

Or, to simplify things for the operator, one could measure each subject and look for a “normal” temperature of 91F to 94F without making any adjustments or offsets. A higher reading might indicate a fever. Still, such a scan could not be regarded as a reliable absolute measurement of core body temperature, only a scanning or screening indication.

If the general-purpose IR thermometer has a laser-pointing feature, it is best to turn the laser off if possible (or cover it with tape) and always use great care to avoid pointing it at someone’s eyes. The laser is not part of the measurement technology and is only used to assist in aiming.

1. I have an instant read IR thermometer,

mainly used it in the kitchen. I started pointing it at my forehead back in March. It consistently says 95.3 - 95.7. I noticed the ones you see on TV look like the same sort of thing, I guess that "mathematical adjustment" of adding about 3 degrees is the difference.
