Fever is one of the most important vital body signs. Monitoring fever in an early stage will allow for a quick and active response. Omron pays the highest attention to the development of functional and accurate fever monitoring tools. The Gentle Temp 520 ear thermometer uses highly accurate technology and includes features such as a one second measurement and a memory for up to nine readings to track temperature changes over a period of time and monitor trends. It also comes with 21 probe covers. Temperatures can be displayed on the large LCD display in either degrees centigrade or fahrenheit.
