The Harpenden Neonatometer is designed to accurately measure an infant's length to the nearest millimetre while the baby remains comfortably lying on a flat surface, eliminating the need to lift or reposition the subject.
Its smooth ball-bearing carriage glides effortlessly and is controlled using a constant-pressure lever that automatically secures the carriage at the correct measuring position. This advanced mechanism ensures consistent, repeatable measurements while minimizing variations caused by differences in operator technique.
