The HVL-CS is an ergonomic digital chair scale designed for patient comfort and ease
of use in the hospital / nursing home environment. The weight is displayed on a
battery powered digital indicator in clear numbers on a high contrast liquid crystal
display. The chair is supported on a five wheel frame, and safety brakes are provided
in all five wheels. A footrest at the front allows the patient to sit comfortably in the
chair. For moving the scale between locations a convenient push handle is fitted at the
rear of the chair. All surfaces are easy to clean and may be wiped with a damp cloth.
