Aviva Optical Supplies is located in Willetton, WA and specialises in offering custom-made optical essentials and accessories. Braun Thermoscan Digital Ear Thermometers from Aviva Optical Supplies help parents and medical care givers take children’s temperatures in the most unobtrusive manner possible. One of the most used brands of thermometers in the United States, they give the temperature readout in a matter of seconds reducing discomfort and mental distress for sick babies. Braun Thermoscan Digital Ear Thermometers take the temperature by measuring the heat generated by the eardrum and surrounding tissues. The tip that is inserted in the ear is tiny and soft and is designed with the needs of very young sensitive children. The tip is protected by a cap to protect from damage. A clear LCD display gives the temperature measurements for 34 degree Fahrenheit to 42.2 degree Fahrenheit and from 93.2 - 180.0 Celsius. A beep indicates to the nurse, doctor or parent that the thermometer is ready to use or that these temperatures have been taken. When not in use these ear thermometers automatically turn off after 60 seconds as a safety precaution. The Braun Thermoscan Digital Ear Thermometers work on alkaline batteries, which are included in the pack.
