Why measure in the ear? The ear canal is the best site to measure a fever because of its close proximity to the eardrum, which shares the blood supply of the brain's temperature control center. This site allows for a more accurate reflection of the body's core temperature.

• Exclusive pre-warned tip technology is designed to minimize the cooling effect of the tip inside the ear canal, providing accurate measurements time after time.
• Unique positioning system uses a light and beep to confirm proper positioning.
• Protective case with lens filter
• 2 AA alkaline batteries
