Remote Sensing Keychain Thermometer

I like it.

From the website:

Touchless Keychain Thermometer

Breakthough technology gives instant temperature readings!

Just aim and press the button!

Balance the A/C ducts in your house.

Find areas that could use more insulation.

Check your coffee, the bath water, the oven, your computer, engine components... it's useful and, well, fun!

Works from -27°F to 428°F (±2.5°) and can be switched from Fahrenheit to Celsius.

Batteries included.

When I first saw a consumer version of these hand-held no-touch thermometers early last year I was so impressed I featured one and then bought it.

I paid $71.84 but I guess Moore's Law is somehow involved 'cause just now when I went to the site where I bought mine (to make sure it was still available) I saw that it's now priced at $37.43.

Huh.

A couple months ago a pocket-sized version appeared, for $39: I'll bet that's the sort of thing that caused the price drop.

Anyway, the keychain version takes it to the next level in terms of size and usefulness.

$79.95.
