The large, 3-door glass draft shield allows for precise weighing or small items. Easy to operate, the balances are calibrated either internally or externally using a calibration mass. The large, backlit LCD allows a clear presentation of the weighing results. To achieve the best possible weighing conditions, the balances feature a filter level setting that can be adjusted to a fast or slow mode depending on the working environment. Other features include quick access keys, balance taring, balance zeroing, auto switch-off, and backlight turn-off time. The balance features several databases for recording users, products, weighings, and tares. Only users with appropriate access can adjust balance settings, export data, import data, and delete records. Two USB, two RS-232 interfaces, Ethernet, and Wi-Fi port offer external connection to a computer or printer for GLP/GMP-compliant output. These NTEP-approved balances are tested and evaluated to ensure they meet all government standards and requirements set by the National Institute of Standards and Technology (NIST).
