The ENIGMA digital mini scale is designed for maximum capacity. The extra-large 4" square platform, high precision sensor, and included expansion trays make the ENIGMA one of the most versatile pocket scales around. For safe storage and transportation, the large expansion tray fits over the scale while the smaller tray keeps the platform covered and protected. This scale is ideal for weighing medications, jewelry, and other items that require incredibly accurate measurements. Results are easy to read on the green back-lit LCD in any lighting condition.
