The Platform Scale is durable with a solid aluminum platform under a stainless steel top. The load cells are encased in aluminum channels to protect against damage, plus a heavy ribbed vinyl mat is included. The scale provides exceptional accuracy, within 0.2% at 300 lb, and can be re-calibrated at the clinic. The scale will auto lock on the weight even if the patient won’t sit still. It can be attached to a wall with the sturdy adjustable wall mount bracket (included) or on top of a cabinet. The scale has a 2-year limited warranty that covers all parts and labor, excluding the vinyl mat.
