Heavy-duty, yet lightweight, the 6855 bariatric scale's balanced design makes it easy to move. The 6855 is engineered specifically for weighing obese and unsteady patients and features a 18" x 14" (457 mm x 356 mm), low-profile platform with non-skid surface and sturdy handrails with padded grips. The display "hold" feature retains weight so you can attend to the patient first, then record the weight. Powered by your choice of either batteries or AC adapter, the 6855 also has an auto-off function to conserve energy.
