Taylor Precision Products High Temperature Digital Thermometer Instantly read temperatures from the easy-to-read LCD display on this pocket thermometer. With a temperature range of -40 to 500 degrees Fahrenheit or -40 to 260 degrees Celsius, this thermometer updates the temperature every second. A 5-inch long, 3/8-inch wide stainless steel probe stem reaches deep and cleans easily, with a protective storage sleeve that clips to pockets or straps. With its flattened profile, never worry about the thermometer rolling off tables and other flat surfaces. Keep the included 1.5-volt battery running for extended use with the on and off button.
