The Detecto Digital Patient Lift Scale is supplied with two spring "O" rings.
Note: Patient lift itself is not included.
Warranty: 2 Years - Free from Defects in Material and Workmanship.
The Patient Lift Scale determines the weight of a person suspended from a portable patient lift mechanism. It is easy to operate, with each scale having only three keys: "On/Zero," "Off," and "LB/KG" to simplify the weighing procedure.
Readouts are large, making patient weight easy to determine. The Lift Scale operates on one 9 V battery (not included).
This completely self-sustained instrument's operation is quickly and easily learned, setup is easily done, and the lock-weight feature stores the last weight reading when the unit is turned off.
