Now you can tell in an instant how hot that BBQ, radiator cap or A/C output is—without having to even get close to it! This hand-held thermometer will read temps from -35 degrees all the way up to a very hot 689 degrees, but from yards away. Use this to discover weaknesses in tires, defects in construction, expensive energy leaks and a whole lot more. We’re told our price on this is so low it’s making our competitor’s blood boil, but we’re waiting to get an exact temperature on that. Seriously, these thermometers are super-handy. Get one before they’re gone.

Incaccurate readings will result from measuring shiny of polished metal surfaces. To compensate, cove the surface to be measured with masking tape or flat black paint. Allow time for the tape to reach the same temperature as the material underneath it. Measure the temperature of the tape or painted surface.
