Measuring scanner
From Wookieepedia, the Star Wars wiki.
A measuring scanner, or cargo scanner was a scanning device used by smugglers and freighter captains to figure out which cargoes fit best into which cargo bays. Measuring scanners calculated mass and volume, and could also be programmed to take into account dimensions and density of almost any object. They could not identify the contents of sealed cargo cases though.
One popular model was the hand-held Fabritech A-11 Cargo Scanner which was very easy to operate and had a radius of 10 meters.
