PS400 Slimline Portable Bench Scale is strong, robust and easy to use for weighing up to 400 lb. Low-profile, aluminum die base comes with a hard-wearing, diamond-tread pattern to help stop packages from sliding off the scale. Compact, ABS plastic indicator uses a 10' long coiled cable, allowing you to mount the indicator on the wall if needed. Dual-powered platform operates on the included AC adapter and four AA batteries (not included). Long battery life lasts up to 168 hours, making it ideal for portable applications without the need to locate a power outlet. Bench scale features three simple-to-operate keys and a highly visible LCD with 1.2" high digits to quickly ship packages out the door with very little training. Slimline is a perfect solution for a wide range of warehouse shipping/receiving areas, mailrooms and other general weighing applications.
