Calculated Industries, best known for its line of specialized calculators, recently introduced a newly redesigned model of its DigiRoller measuring device, the DigiRoller Plus III. The DigiRoller Plus III can measure lengths, widths and heights in either U.S. or metric units. Plus, it can calculate areas, volumes, perimeters and more. It has easy-to-use (and read) handle-mounted controls with a seven-digit backlit display. The gear drive is sealed for better protection and the centerline design gives it good balance and 99.5 percent accuracy. The Digi Roller III has a kickstand for when you’re “parked.” It comes with a backpack/carrying case, a 9-volt battery, reflective safety tape, a wrist lanyard and a two-year warranty. ?
