The Model 684 by Seca facilitates safe weighing while the patient is standing, sitting or in a wheelchair — without having to be converted. When standing, the patient is supported by a stable handrail; when sitting, by an integrated folded seat; and when in a wheelchair, by a large platform (31” x 38”) — the weight of the wheelchair is simply tared away by the pre-tare function. Results are easy for patient and caregiver to read from the swiveling display mounted at a convenient level.
