The high capacity of 800 lbs of this digital wheelchair scale means that even heavy patients can be weighed with ease. Thanks to the extremely flat platform, the scale is easy for wheelchair-users to mount and the side barriers ensure maximum safety. The integrated pre-TARE function determines the patient's net weight in seconds and a real advantage is its HOLD function, which continues to display weight in large, easy-to-read numbers even after the scale is no longer in use. The Seca 664 can fold up in just a few easy steps, and its transport castors make it convenient to move.
