Versatility is the watchword with the Polder dual sensor thermometer and timer, which measures both the internal temperature of your food and the temperature of your oven at the same time. With its stacked temperature displays and 10-hour timer ( nine hours, 59 minutes, and 59 seconds, technically), the Polder thermometer is both functional and efficient. Its temperature readings range from 32 to 572 degrees F, though the temperature ranges for the pre-settable timer run from 85 to 572 degrees F (which is fine, as you'll rarely have to cook something at a temperature below 85 degrees). Keep a careful watch on your next roast with this thermometer timer. Put the probe in your meat while keeping the thermometer/timer on the counter top. Quickly opening the oven door to read the temperature and let minimal cold air in is no longer a chore. The timer is versatile, too, with count-down, count-up, and overtime count-up features. The thermometer even comes with a USDA cooking chart, with recommended temperatures and times for a variety of foods.
