It has a capacity 660 grams and reads in 0.1g increments. The protective hinged cover doubles as an expansion tray. Also it is now included a rubber coating on the outside of the scale, so now the Triton series is more durable then ever! Uses 2 x AAA Batteries. Lifetime / 30 year best-in-industry warranty. Large easy to read LCD display, and three soft rubber keys combined with the unique hinged - yet removable cover make this scale a true winner.
