With Detecto's 6495 heavy-duty USA-made wheelchair scale, you receive digital speed and increased accuracy that only electronic weighing can provide. The display is mounted on a ball-pivot mount swivel, so that it can be positioned wherever it's easiest for the patient and medical professional to view. An alphanumeric keypad for entry of known weights of empty wheelchairs speeds the process, providing the weight of patients instantly on the MedVue 1LOOK indicator. Sturdy steel construction and a ramp with non-skid surface further ease wheelchair weighing operations. The scale also features RS232 serial, USB, and optional wired or Wi-Fi Ethernet for connectivity to EMR/EHR in healthcare facilities. Powered by 6 C batteries (not included) or optional AC adapter. 800 lb x 0.2 lb / 360 kg x 0.1 kg capacity.
