The SR453i Platform scales are used as weighing stations for a wide variety of applications. The SR453i has a large weighing surface with integrated ramps that will easily accommodate patients with walkers, canes, wheelchairs and dialysis chairs. The scale is constructed of heavy gauge aluminum with a weight capacity of 660 Lbs (300 Kg). This multi-purpose scale is strong. It features a dual function display with bright 16 character dot matrix L.C.D to view both patient net weight and relative weight change simultaneously. A freeze mode allows the caregiver to “Freeze” the displayed patient weight and make adjustments for the patient’s comfort and then resume weighing without affecting the patients net weight. The power is a UL approved wall power supply with auxiliary alkaline battery power back up.
