1.0 Introduction

The Rice Lake Digital Handrail Scale 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 scale is set up to use motion sensing weighing 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.
