Review on White Digital Thermometer - Instant Accurate Reading, Fever Alarm, and Memory Function - 3 in 1 LCD Display for Adults, Kids, and Babies by Matt Larsen

Love that this instrument came right out of the box and was accurate. The instructions were very clear, concise and easy to understand. You can adjust the scale (C/F). The default is Fahrenheit. The upper trigger point is adjustable and the deviation from the baseline can be adjusted if necessary. You can also set it to read in body or surface mode. Again, for simple body temperature, I found that no adjustment was needed for these parameters. A very accurate instrument at a very reasonable price. (Requires 2 AAA batteries, not included)
