Opening the oven to check on a food's temperature means wasting the cook's time and losing oven temperature and moisture not to mention a face full of steam. This thermometer prevents those problems. Insert the instrument's 6 inch stainless-steel probe into a roast beef or turkey and monitor the time and temperature (from 32 to 392 degree Fahrenheit) on the thermometer's large digital display, which connects to the probe with a 4 feet cord. The control panel sets cooking time and temperature and an alarm sounds when either is reached. Fully opened, the thermometer/timer is 5 inch high, but it folds flat for compact storage. Magnets on the back permit it to be temporarily mounted on a metal surface.
