The perfect scale when you know you will need to move it regularly within a facility. Just "tilt and roll" from one location to the next. No need to disassemble or pack in a carry case. Never need an AC power supply or recharging with the PS-8070, which uses 6 "C" batteries and provides up to 80,000 measurements. Very similar to the best selling PS-6600, it has a black LCD display instead of LED. It also features "push button" calibration, a large 16" X 18" "super tuff" cast aluminum platform, accuracy of +/- .1 lb., 500 lb. capacity, with a 3 year manufacturers warrantly. MADE IN THE USA!
