This beam scale proved to be the best in tests by the Hammacher Schlemmer Institute because it is consistently the most accurate. An independent industrial weighing systems company was commissioned to calibrate the scales prior to testing and this beam scale was the most precise, only deviating from the actual weight by 0.35% on average, unlike lesser models with inaccuracy rates up to 1.2% (2 lbs. for a 180-lb. person). Scoring highest for consistency, the scale was the only one that recorded three spot-on measurements of seven different weights, while the unit that placed second failed to record even one exact measurement. The scale has a 500-lb. capacity and measures in 1/4-lb. increments, the poise bar rotates to show measurements in Imperial or metric, a 24" to 84" height rod slides out of the unit to allow simultaneous height and weight measurements, and the engraved markings are easy to read. The scale is made from heavy-duty steel and assembles in 10 minutes. 57 1/4" H x 10 2/3" W x 20 1/2" L (39 lbs.)
