Health O Meter 500KL Scale Overview

The Health O Meter 500KL Eye Level Digital Scale is one of the most used and trusted scales in hospitals, doctor's offices, care facilities, and other professional medical settings. Featuring a built-in height rod, BMI calculation, and digital interfacing with electronic medical records (EMR) software, the 500KL scale offers exceptional value and convenience to any professional setting.

The scale that medical professionals have come to depend on has recently been upgraded to offer even more functionality. Among the upgrades are a higher weight capacity of 550 pounds as well as the patent-pending Everlock feature, which allows users to permanently lock the unit of measurement to pounds or kilograms. Other new features include recall, reweigh, and pre-tare functions.

This scale fits in seamlessly with the modern medical office. A USB port on the back of the display head allows it to communicate with computers and monitors, electronic devices, and EMR software to easily integrate with patient records. Because patients are not one-size-fits-all, the high weight capacity accommodates a wider range of body sizes and the low-height platform makes it easier for patients with limited mobility to step on and off the scale.

The Health O Meter digital scale is durable to withstand frequent use and can be powered two ways: with six AA batteries or an optional AC power adapter. The power adapter can be purchased separately (product number ADPT31) or with the scale (product number 500KLAD). The estimated battery life when the auto-off feature is activated is 7,000 readings.

Why Buy This Scale?

Several features set the Health O Meter 500KL Eye Level Digital Scale apart as one of the most trusted scales for professional use.

Convenient BMI Calculation. The BMI function allows the patient's body mass index to be calculated with the scale.

Electronic Medical Records Connectivity. This digital scale features a USB port and will interface with computers and other devices as well as electronic medical record (EMR) software for easy integration into today's digitized medical offices.

Everlock. This option allows the scale to be permanently locked into either pound or kilogram measuring units.

Durable Low-Profile Platform. The scale platform is dent- and rust-proof to stand up to heavy use in professional medical settings. The low platform height makes it easy to safely step on and off even for patients who may have mobility issues.

Attached Height Rod. The built-in height rod is easy to use and ranges from 30 to 84 inches. When not in use, the height rod can be folded down so that it's out of the way.
