Infrared Thermometer, $29 with code UH9XRRMS

Update: The price was listed incorrectly. The final price with promo code is $29.

This industrial level IR thermometer can read temperatures ranging from -58° F to 1,022° F. But I normally use mine for much simpler things, like to fact check my oven temperature, check for air leaks, or really just play around with. At $18 with promo code UH9XRRMS, it’s well worth it for the entertainment factor alone.
