D Series
The D series, with its simple design, large round stainless steel weighing surface, hard buttons operation, and blue backlight display, has been popular since its appearance. The Diamond model in this series reaches the precision of 20.001 Gram. Its high-quality performance can ensure the precision in the absence of a protective cover. The six different measurement units (Gram - Carat - Pennyweight - Ounce - Troy ounce - Grain) can easily be converted. Its fine and practical leather cover and high-precision standard weight included make its use very convenient. Professional quality, life-long warranty, and very good price make the series very recommendable.
