The Escali Pico High Precision Digital Scale is an ultra-sensitive, ultra-portable hand-held scale that measures with increments of 0.005 ounce or 0.1 gram. The Parts Counting function will allow you to count large quantities of small items, and the Display Hold feature will allow you to see measurements when a tray or plate is blocking the view of the display. Reset the scale to zero weight to measure multiple items or subtract the weight of container. The scale will turn off after five minutes of inactivity to help conserve and extend battery life.
