To ensure sanitary temperature monitoring, this Non-Contact Infrared Thermometer is designed for multiple purposes: forehead, bath water, milk bottles, rooms and more. Touchless design makes it easy to use. Three-color back light makes it easy to read. Thermometer alerts you to a fever with a special alarm and recalls up to 32 past readings with its built-in memory. It measures temperatures in Fahrenheit and Celsius for its three modes (body, surface and room). Thermometer shuts automatically after 30 seconds of nonuse to save battery life. It runs on two AA batteries (sold separately).
