Cook perfectly pink roasts and toast with wine served at ideal drinking temperature with this instant-read digital thermometer. After being inserted at least 1 inch into the food, the 4-3/4-inch stainless-steel probe accurately displays the temperature in just 8 seconds. One button changes the LCD display from Fahrenheit to Celsius, while another turns the device on and off. A rubber cap can be pried off in order to change the battery, while a plastic sheath with pocket clip lets the user keep the thermometer close at hand. To determine the accuracy of the thermometer, fill a container with chipped ice and water. Insert the probe 2 inches into the water without touching the container bottom. If the temperature reads less or greater than 32 degrees Fahrenheit, the thermometer can be recalibrated. By means of a small screwdriver, a button on the display top can be turned to the left to decrease, and to the right to increase the temperature reading. This thermometer ranges from a low of -58 degrees F(-50 degrees C) to +500 degrees F(+260 degrees C), and is covered by a 1-year warranty.
