The BC60 scale is a perfect choice for PC-Based carrier shipping systems that do not require USPS letter capability. Ideal use for ecommerce and retail shops. It is compatible with shipping systems from UPS, FedEx, DHL and other shipping software. Mettler Toledo's GEOCAL calibration feature eliminates the cost of having the scale site-calibrated. By compensating for local gravitational differences, GEOCAL ensures that the factory calibration is maintained.
