· The Ubbi Stingray Bath Thermometer delivers fast and reliable water temperature readings so you can ensure the perfect bath every time. · Crafted from baby-safe platinum silicone, this baby bath thermometer is designed to be gentle in the tub and safe for everyday use. · A red light flashes and “hot” appears when water exceeds your custom set temperature (up to 80°C/176°F), while a blue light and “cool” appear if the temperature drops below 30°C/86°F—helping you keep baby bath time both safe and soothing. · Switch easily between Celsius and Fahrenheit with a quick tap, and press and hold to adjust the high temperature alert setting to your preferred levels. User-friendly buttons make setup a breeze for any parent or caregiver. · The baby thermometer disassembles for cleaning and dries quickly. The battery-operated thermometer uses lithium free LR44 batteries (included). Smart auto sleep kicks in after 15 minutes out of water or 30 minutes in water to preserve battery life.
