Designed to be used with the utmost ease, Detecto’s digital baby scale can weigh even the most active baby. With step-by-step instructions right on the keypad, there’s never any question about what to do next. Features lock-in weight ability, built-in battery charger for NiCad or NiMH batteries (15 hours charging time), a locking pin for easily removing the tray for cleaning, and sleep and auto-shutoff modes to extend battery life. This digital baby scale has a lock-in weight feature which compensates for typical newborn movement. When weight stabilizes, it is ’locked in’ and displayed. The infant can be removed and its weight is retained. The scale features a built-in battery charger, battery or AC power, and a built-in measuring tape.
