Detecto's versatile 6400 portable, low-profile wheelchair scale features a high 1,000-lb/450-kg capacity, two-way easy-access ramps, flexible cable remote display for tabletop or wall-mount viewing, 2.2-in/5.6-cm thin platform for easy accessibility, 0.2-lb/0.1-kg clinical accuracy, black rubber mat for traction, two guide handles and two wheels for vertical transport mode, and 32 in x 36 in / 81 cm x 91 cm platform size. Despite their size, these wheelchair scales are amazingly easy to handle. Since the display is connected to the scale by a long coiled cable that extends up to 14 ft / 4.2 m, it can be positioned where the healthcare professional can most easily read the results. The 6400 comes with the model 750 indicator for easy-to-use, basic weighing functions, including BMI calculation, RS232 serial port, and big bold LCD digits. Powered by 6 AA batteries (not included) or optional AC adapter.
