The Tree SC-76 Digital Postal Shipping Scale is great for small to medium sized package and parcel weighing for postage calculations when mailing with UPS, USPS, FedEx etc. Weighs in g, kg, lb, oz, lb:oz and offers a high 76lb maximum capacity and a resolution of 0.2oz. Nothing fancy here, just a good old basic scale that is a very economical solution for people that need a scale that will do the job. It does have an AC power option, but it does not come included. We do sell them, so please let us know if you need one with your SC-76. If you require a lower resolution/readability, we also sell the SC-36
