Here is another smart thermometer that can measure temperature of surfaces without any contact. The AnnMeter infrared thermometer has a range of -58 to 1472F. Simply aim it at any spot and pull the trigger to get a reading in 0.5 second. The device has enough memory for 20 readings but you can always sync the data to your iOS/Android phone.
This temperature gun has a LCD display with backlight. Its high/low alarm alerts you to abnormal conditions while you maintain a safe distance.[where to get it]
