The 245EHR-3105 uses solid-state technology, which provides a facility confidence that a patient's height will be measured accurately, and workflow will not be interrupted. The built-in reset feature increases accuracy and reliability, and the folding headpiece limits the height rod's profile, providing safety to patients and caregivers. The market-leading height rod provides the most accurate height measurement in its class, with a graduation/resolution of 1mm/0.1" and a full measuring range of 11 ¾" - 79 ½" / 30cm - 202cm and a digital range of 3ft 11.2" - 6ft 7.5" / 120 cm - 202 cm
