The Safety 1st Digital Thermometer is a simple to use device that is just great for digitally displaying rectal, oral and underarm temperature. It can give a swift read out in 40 seconds in case of rectal temperature and within 60 seconds for oral and underarm temperatures in Celsius/Fahrenheit. It features a flexible tip and an over-insertion gauge. You get a visual indication when reading is complete and last temperature reading is also stored in the thermometer. An On/Off switch for convenient usage with an automatic switch-off stretches battery life. A 'low battery' display is built in. An automatic self-test ensures the accuracy of the thermometer. A protective storage case comes in handy.
