p The Medisana Thermometer FTO is an infrared ear thermometer that measures your body temperature quickly (in one second) and accurately. This thermometer can also be used to measure ambient temperature, liquids and surfaces. The Medisana Thermometer FTO measures the infrared energy emitted from your eardrum. (The ear is an excellent site to measure temperature accurately.) The ear thermometer has a memory function that allows you to store the last 12 measurement results. The sensor can also be used to measure the temperature of liquids, surfaces or the environment. The Medisana Thermometer FTO comes with a manual, storage bag, battery, protective cap and alcohol wipes. Conversion from Celsius to Fahrenheit is possible, if desired. The thermometer emits an acoustic signal (10 short beeps) if the measured body temperature is above 37.5 Celsius. /p
