Height rod for infants. The carefully designed novel shape of the Seca 416 Infantometer is the easiest and simplest way to measure babies and infants up to two years old. The raised sides hold the baby safely and securely in position, while the foot piece slides smoothly along the measuring scale. The foot piece is also completely lockable, allowing the result to be saved while the baby is tended to. All parts are of durable and robust quality.
