Save time and money with the heavy-duty, portable DYMO S400 Digital USB Shipping Scale. You can quickly and easily weigh large packages up to 400 lbs at 0.5 lb increments for precise shipping. And thanks to the built in handle, you can carry the scale to the items, instead of hauling them to the scale. The handy ‘Hold' feature displays weight for 10 seconds after you remove the item which makes it easy to weigh heavy and bulky packages. Plus, this package scale has an automatic shut off that extends battery life and a convenient detachable LCD display. Connect via USB cable to PC or Mac* to use the scale with popular online mailing and shipping software. *Microsoft and Windows are either registered trademarks or trademarks of Microsoft Corporation in the United States and/or other countries.
