The BC-6L replaces the model PS6L, the granddaddy of postal/shipping scales and the preferred scale of mail and parcel centers. The BC-6L comes with a larger and brighter display. Accurate to 1/10th of an ounce. Weighs light letters as well as heavy parcels. The BC-6L meets USPS accuracy specifications and is NTEP approved for legal-for-trade applications. The patented GEOCAL feature eliminates the need for on-site calibration and insures local accuracy with calibration compensation.
