This is a dedicated underarm thermometer for babies. It provides a 30-second speed measurement (average predicted time). It allows for quick temperature taking even for babies who don't stay still. Actual measurement is also possible (approximately 10 minutes). It fits snugly in the baby's armpit and is easy for mothers to hold and handle. It has the perfect angle and length for a baby's armpit. The large temperature-sensing area makes it easy to take a temperature. It has a light that makes it easy to place under the arm. You can check the measurement location even in a dark room. The large, easy-to-read LCD displays to two decimal places. It has a previous measurement memory function that displays the previous measurement value when turned on. It has an auto power-off function. The battery can be replaced. It comes with a storage case.
