SPECIFICATIONS FOR THESE SCALES
General
The Model 2500KL and 2600KL Digital Wheelchair Patient Scales use highly sophisticated
microprocessor technology. Each precision scale is designed to provide accurate, reliable, and
repeatable weight measurements. In addition, each scale is designed to provide the user with
features that make the weighing process simple, fast, and convenient.
These scales are set up to use motion-sensing weighing technology in order to determine the
actual weight of a moving patient.
Weight can be displayed in pounds or in kilograms. The scale features a 180°swivel display
head for privacy and for easy operator reading from either side of the scale. For easy mobility,
the 2500KL Scale has 2 built-in wheels, along with the 2600KL Scale with 4 built-in wheels.
Both scales can be powered using an AC Adapter (included), or by 6-AA batteries (not
included).
