1.0Introduction
The Rice Lake Digital Bariatric Handrail Scale with fold down seat is designed for weighing bariatrics and
ensures sound, accurate weighing information. A non-skid platform paired with side rails assists persons who
need extra support and safety. The fold down chair allows patients to sit down while being weighed. The scale is
set up to use motion sensing technology, to determine the actual weight of a moving patient. The weight is
displayed on the indicator and can be displayed in pounds or kilograms and has a 1000 lb capacity.
