Don't take any risks whilst bathing your little one! The Chukles bath thermometer provides a safe and comfortable bath for both child and parent. It is easy to use with no power switch and operates using a water sensor. Place the thermometer directly into the bath and watch it instantaneously display the water temperature on the digital LCD screen, which has a coloured backlight for quick and easy indication. Orange = too cold, green = just right, red = too hot. It's as easy as that!
