Accurately and safely measure body temperatures with this medically certified San Jamar non-contact infrared thermometer. Simply point at the forehead and click the trigger-mounted button - temperature is displayed within a second. The large and easy-to-read LCD screen will light up green, orange or red to indicate normal, elevated or high temperatures. If a raised body temperature is detected, the thermometer sounds an integrated alarm too. Because it\'s lightweight and battery-powered, it\'s a great portable option to help you carry out temperature checks on customers or colleagues. An automatic power-off function will activate after 30 seconds to further extend battery life and cut down on the cost of buying in regular replacements. When the time does come for new batteries, the display screen will inform you in advance so you\'re not caught out with no power. Temperature range: 35°C to 42.9°C Contactless temperature reading
